The New Version of Our SG Optimizer Plugin Is a Game Changer for Your WordPress Performance

Early versions of our SG Optimizer plugin had one single purpose: to connect WordPress with the reverse proxy caching system set up on our servers. Over the years, we have added multiple features like PHP and HTTPS management options that allow even more control over SiteGround’s server environment right from the WordPress backend. With the new release, not only have we greatly enhanced the existing functionalities, but we’ve also included some of the most popular application-based performance optimizations. Now, our plugin is an all-inclusive performance solution for WordPress sites hosted on our platform. Our SG Optimizer has always been an invaluable tool in boosting site performance and now we’ve pushed its capabilities even further. Internal speed tests of the new version show an additional 20-30% performance improvement even for well-optimized sites. And when you use the plugin on a site that runs on an old PHP version and/or has poorly-optimized content, the benefit can easily go up to 500%!

Smarter Dynamic Cache Purging

The NGINX-powered full page caching has been a core functionality of the plugin from the start. Now, we have significantly enhanced that feature by improving the cache purge functionality. Before this release, any time there was a change on your site, even just a new comment on a blog post, the plugin purged the cache for the whole site. This meant that many visitors would see non-cached content, causing slow page loading times. With the new version, we purge the whole site cache only when there are important changes like when you update your WordPress version or install a theme or a plugin. On all other occasions, we have smart rules to determine which part of the cache to flush. For example, when someone publishes a comment on your blog post, only that post’s URL will be cleared from the cache and regenerated on the next visit. The less your cache is purged, the less times your site will be reloaded.

Brand New Front-End & Image Optimizations

A whole new set of front-end and image optimization features are now part of our plugin. Most of them are well-known and widely used application level optimizations that make WordPress sites faster. What’s unique to us is we’ve designed our plugin specifically for the SiteGround environment in order to minimize the resource footprint the optimizations cause.

  • Automatic image optimization option for new uploads and manual bulk optimizer function for old ones.
  • Lazy loading of images that reduces the initial loading time of your pages and is especially useful for long ones with lots of images like the blogroll page.
  • GZIP Compression to compress your content before it’s served to the browser and save bandwidth.
  • CSS, JavaScript, and HTML minification that improves the loading speed of your site by reducing the size of your resources.
  • Remove query strings from static resources to improve the way your content is cached by your visitors and potentially your CDN, if you’re using one.
  • Option to disable emoji support to avoid unnecessary overhead by the emoji conversion script.
  • Browser Caching Control that automatically adds the necessary rules for your visitors’ browsers to cache your static content longer than the default settings.

Improved HTTPS Traffic Redirect

In the old plugin version, we used to redirect the traffic to HTTPS dynamically, which is not optimal because it adds to the loading time of your site. Although the footprint was minimal, it was still present. In the new plugin version, we have split the process of forcing HTTPS on your site into two steps. First, we update your database, re-configuring your site to work with your SSL certificate and place a redirect to HTTPS. For the majority of sites, that’s enough. However, depending on the code of your theme or plugins, some resources may not be in the database. In these situations, when your site gets loaded in the browser, you will see the red warning “insecure content” on the page. Our second feature is designed in case there’s content not covered by the first one. The “Fix Insecure Content” toggle will scan for insecure content and dynamically rewrite those for you.

Other Functionality Improvements

Beside the main functionality enhancements listed above, the new version of our plugin has brought a number of smaller but handy improvements to several other areas:

Better Memchached support

We’ve enhanced the Memcached support in the new plugin version. Previously, additional tweaking was required when  changing the PHP versions of your site. Not anymore! The Memcached works smoothly with all PHP versions supported by SiteGround. Our improved implementation also allows you to see statistics about which objects are served via Memcached for each page. These stats can be visualized with the help of the Debug bar plugin.

Easier PHP version change

When checking your site for compatibility with the recommended PHP version, we now run more optimized checks that save time and server resources. We also made switching between different PHP versions easier.

All functions available through WP-CLI

WP-CLI provides easy command line site management, but until now, we weren’t using WP-CLI to its full potential. Now, we’ve expanded the commands and you can change every option in the Optimizer backend through your command line.

Sleeker Interface for Single Site and Multisite

The new version of our plugin introduces a simpler, cleaner look and feel.  Its interface is now fully redesigned and written in React, which allows us to better handle processes and perform tasks that can take a longer period of time without stalling or exhausting too many resources for a short period of time.

The Multisite controls allow administrators to perform bulk actions across their network and are now easier to find and use. They are all neatly listed in a single section of the plugin instead of in different places in the general multisite WordPress admin panel.

Other Performance Plugins Compatibility

As SiteGround clients, you know our platform is compatible with all sorts of third-party plugins. That’s intentional. Unfortunately, we see that many performance plugins cannot achieve the most optimal performance results because they are designed to generally work well with multiple hosting platforms, rather than generate the best possible results for a specific platform of which they might not know the ins-and-outs. That is why we decided to step up and offer an all-inclusive solution specifically shaped to the characteristics of our environment, creating the best possible performance for sites hosted with us.

That being said, as always, it is up to you which plugins to use given that you are the expert in your business objectives. However, should you choose to use a specific plugin that has an overlapping functionality with the SG Optimizer plugin 5.0, we recommend you disable that option in the SiteGround Optimizer interface. Instead of making your site faster, two plugins trying to achieve the same thing may actually make it slower.

NOTE: Whenever you upgrade to or install the new plugin version, we will check if your WordPress is already using another performance plugin that may have an overlapping functionality with the SG Optimizer. If this is the case, the overlapping options in our plugin will be automatically switched off. You will need to switch them on manually if you would like to use them through the SiteGround Optimizer.

    Something in the optimiser is breaking ninja-popups though. I get

    As of updating, my staging subdomain was thrown up live, and after first support contact, fixed, but now the staging sub is no longer accessible with wp-admin. Support not getting back to me. I see you've even thrown up 5.0.3 so I'm guessing you've got your hands full with this misstep.

    • Reply December 4, 2018 / 03:24 Hristo PandjarovSiteGround Team

      The problem is caused by the object caching and the fact that you've cloned your sites including the salts during their creation. Sites sharing salts is a very bad idea when it comes to security and object cache usage. I've asked our support team to update your ticket and regenerate the salts on one of the sites in order to avoid such issues from happening.

    First, thank you for providing us with some major improvements, as I tested version 5.0.3 on my site. Many new features look really great and beneficial.

    A site I manage : diethylstilbestrol.co.uk has 1050 posts and 1142 media items. So, when I removed plugin "EWWG Image Optimizer" to run your new function of "Images Optimization" and "Existing Images Optimization" I was logically told to "PLEASE BE PATIENT, THIS PROCESS MAY TAKE SOME TIME".

    Well, there seems to be a bug, as it has ran for almost 12 hours and still "not completed", showing a kind of never-ending loop.

    Can you please let me know what I should do - or if this will be fixed with 5.0.4 ?

    Does the minify & combine of CSS and JS bypass plugin scripts? I've just enabled it on a test site and it has not merged anything, but has compressed a single file slightly further than it was.

    • Reply December 6, 2018 / 05:03 Hristo PandjarovSiteGround Team

      We do not combine since we strongly believe that everyone should use HTTPS and HTTP2. Minification does work with plugin and theme scripts. We store the minified version in the same folder to prevent relative links from breaking.

    • Reply December 6, 2018 / 05:13 Hristo PandjarovSiteGround Team

      Generally, for performance sake, it's not a good idea to duplicate functionality - if you're minifying with one plugin, don't minify with another one. Our goal is to have a single plugin to handle all apsects of your site optimization - caching, scripts, images, environment configuration so you don't have to use 3-4 other plugins to achieve all that.

    • Reply December 6, 2018 / 05:09 Hristo PandjarovSiteGround Team

      Generally, avoid duplicating functionality. If you have minifiication enabled in CloudFlare, don't enable it in our plugin. As for Divi - it should work just fine with it since we monitor all the necessary hooks.

      I would say - check out the results you're getting with our plugin. They should be great 🙂 As for your other question - it won't hurt or break anything, just a general rule is not to duplicate functionality. If you're minifying in CloudFlare, simply disable that in our plugin.

    Thanks this is looks like a great plugin and it is really good to see you guys continuing to develop to keep you and us ahead of the game.

    I currently use the jetpack functionality for lazy loading and image CDN along with the old SG plugin and cloudflare CDN.

    Can you give us some guidance as to what we should be using for the optimal setup now. As I can't see that using jetpack and this and all of the Cloudflare will be beneficial and will probably slow it down or cause errors as there is duplication and additional connections.

    • Reply December 6, 2018 / 04:59 Hristo PandjarovSiteGround Team

      That's a great idea for a paper on the best setup on SiteGround. At this point, I would say - try all options and see how they work on your site. As to the CDN, just don't double functionality - if you minify with CloudFlare - do not enable minification on our plugin. Everything else should be fine 🙂

    • Reply December 6, 2018 / 04:56 Hristo PandjarovSiteGround Team

      I am sorry for the inconvenience caused. Optimization plugins touch pretty much every part of WP and conflicts with other plugins happen. I am afraid that those are really hard to predict before releasing the plugin to public. One of the reasons why we use our own auto update system and not the included WP one - we make backups and restore them automatically after update if we notice such error / white screen.

  29. Reply December 5, 2018 / 12:34 Jake OrtmanSiteGround Team

    Very cool. It appears this will replace at least a couple of my plugins (Smush, Autoptimize and Really Simple SSL) along with some of what I had WP Total Hacks installed for (possibly -- I inherited the site, so I'm still learning my way around the various plugins that were used).

    • Reply December 6, 2018 / 04:51 Hristo PandjarovSiteGround Team

      So far, SG Optimizer was only caching solution plus several quick tools like PHP Version switch and HTTPS enforcer and the compatibility between the two was WP Rocket disabling their cache if they figure out ours is running. With the new update, I would recommend that you try and measure how your site behaves with our plugin and new functionality or WP Rocket only. I firmly believe that we've developed the best possible optimization solution for SiteGround customers and that you will no longer need other optimization plugins for your site.

    So I have updated to 5.05 and switched everything on... an impressive GTmetrix score of A 95%, but... Yslow is only C (72%) grade.

    It flags up - Make fewer HTTP requests (F grade):
    This page has 27 external Javascript scripts. Try combining them into one.
    This page has 23 external stylesheets. Try combining them into one.

    I was hoping SG Optimiser would fix this with Minify switched on? is that not the case?

    • Reply December 6, 2018 / 04:48 Hristo PandjarovSiteGround Team

      We haven't added scripts combination functionality on purpose for several reasons. First, the cance for it to break something is big, especially for JS files. Unlike CSS, some javascript relies on the order of loading to work properly. In addition to that, with the introduction of HTTP2 on all our servers, it doesn't make much sense to concatenate scripts. In your case, I would ignore that suggestion, most test services are still running on HTTP1. Measure the end result - how faster your site actually is for you and your visitors 🙂

      • December 6, 2018 / 06:48 DarrenSiteGround Team

      • December 12, 2018 / 12:52 FritsSiteGround Team

        Then I'm wondering why in the description for both js and css files it says: "COMBINE and minify".

        You're right combining these can cause errors. However, I've mostly had great results with the plug-in "Fast Velocity Minify" (which also can combine scripts and caches them).

        My suggestion would be to separate the 2 (as the above mentioned plug-in does, btw): so: 1 option to minify, another option to combine. Then it's easy to see whether it works or not, and - if needed - turn off the option.

        Thoughts?

      • December 13, 2018 / 01:00 Hristo PandjarovSiteGround Team

        That will be fixed in the next update, it's an old string from when we tested combination too. We do not combine files because it's way too dangerous (especially JS files) for the majority of users and with HTTPS and HTTP2 it doesn't make sense to combine resources unless you have extremely high number of those.

    This looks really great! From reading the comments above I saw that Divi should be supported by monitoring the necessary hooks. It looks like I can discontinue the use of WP Smush and be relieved their annoying messages.

    I updated one of my sites yesterday to SG Optimizer 5.0.5 and somehow that site got redirected in total to another of my sites. The client was not pleased. In working with Support (which was excellent as always!) we did a restore from the daily backup and all was well again. I was able to reproduce that error by installing SG Optimizer 5.0.5 again and doing a rollback myself.

    Is it safe to assume that SG Optimizer 5.0.6, available today, has fixed that behavior?

        All is working very well so far. I can tell there is a speed up in load times already.

        Sites with a lot of images are taking forever for the 'existing images optimization'. One site has been churning away since 0900 and it's now 1700. Thanks for adding the 'Pause' button.

        Would it be possible to please add a thermometer or gauge of some kind? That would indicate that progress actually is being made. The spinning circle is nice, but doesn't tell me if there is a hang up or something.

        I do have wp_cron enabled in the wp_config file too... Thanks!

    I had problem where your plug in was shrinking the size of embedded YouTube videos (it made the embedded videos look like a long, thin banner, instead of 800x450 which is what I had the embed code set as) ... .. Is this fix addressed in the latest version?
    Also, I use Autoptimize along with W3 Total Cache, in addition to your SG Optimizer, but since I had the shrinking YouTube video issue, I had to 'roll back' my site to a previous days version and keep an old version of your plug in.... I am now hesitant to update to your latest version due to the shrinking size of embedded YouTube videos ... Are all issues fixed? ... Can I remove Autoptimize and W3 Total Cache and just use your SG Optimizer? Or should I wait for a more stable version? (I asked this in Support tickets and I have been given contradicting answers)

    • Reply December 8, 2018 / 00:25 Hristo PandjarovSiteGround Team

      That looks like an issue with the CSS minification. Try disabling that functionality and it should work fine. We've fixed everything reported so far. In addition, I would suggest that you do not duplicate functionality and leave only our plugin if you are using all of its options. If you prefer using different one for something like image optimization for example - make sure that functionality is turned off in our end.

        That's not a solution (and rather bad advice). Really Simple SSL is a very well tested plugin with over 2 million active installs and a 5 star rating.

        When I turn off the option to use https in SG Optimizer there should be no conflict, therefore, no error message.

      • December 21, 2018 / 02:59 Hristo PandjarovSiteGround Team

        If you're using the SG Optimizer and forcing SSL there's absolutely no need to use the Really Simple SSL plugin. In addition to that, we've intentionally split the HTTPS config into two parts - configuration and enforcing. The second part is necessary only when there are some hardoced resources in your theme or plugins(what Really Simple SSL actually does). The error message is shown after the initial installation / update to the new version and you have to dismiss it. Once you do that, you will not see it again.

      Some themes have issues with minification of CSS, JS or HTML. Check which ones work for your site and just keep the ones that cause issues disabled. Unfortunatelly, not every theme and plugins combination can be minified without problems. Some designs are simply structured in a way that doesn't work well with minification processes.

        Before I pull the trigger and utilize your "Existing Images Optimization" function, just curious if the option to keep the the data was added at anytime and is included in the latest SG Optimizer ?

        I am afraid not yet. Generally, EXIF and IPTC metadata should not be part of your design images. Unfortunatelly, it's a bit tricky to distinguish images used in the design and such as content so if you want to keep that information, please don't enable this optimization.

    Just setting up the new plugin and have a couple of suggestions/ requests.

    I am sure your image optimiser is brilliant. But I had a bad experience with another plugin and am not keen to use it without some sort of trial. It would be great to be able to test it on a couple of images and retain the option to not use it on specific images.

    Also the memcacher is not available on multisites. I don't think this is a plugin issue per se, but it limits the usefulness of the plugin and makes me wonder what I am missing out on?

      Thanks for your feedback, we constantly improve our interfaces and the functionality of the plugin and we will definitelly take it into consideration for future updates.

  61. Reply January 8, 2019 / 10:08 BenSiteGround Team

    I have just removed the functional (but super annoying and sometimes resource hungry) WP Smush, and enabled the Image Optimization settings in SG Optimizer.

    There was little information i could find as to weather SG Optimizer will the same or similar job as the free version of Smush, but its one less plugin to update, one less button, and one less annoyance.

    I did however click the button under "Existing Images Optimization" and was greeted with a "We are optimizing your images, please be patient, this process may take some time."

    This is great, but theres a couple of suggestions i would like to make to this..

    First of all, some form of numerical feedback would be great. WP Smush provided a great deal of information, including how much space was actually saved, and an overall percentage. While that was pretty, it may or may not be practical in terms of resources/speed, so i understand that not being the immediate approach for SG Optimizer. But something would be nice.

    Even something as simple as 100+, 50+, 10+ files left to process. Or even a "Still processing, last checked at 12:34pm". Basically, it would be great to know if the process really is still in progress (i notice 2 others had issues with status/feedback), and hasn't stalled. It would be even better to have a rough idea of how long it was going to take, or how much further it had to go.

    My second suggestion is a little more basic. In WP Smush (at least the free version), "Bulk Smushing" of existing images can only occur if you leave the browser window open. If you closed the window or navigated elsewhere, the process would stop rather than continuing in the background. For everyone who migrates from WP Smush, this is something they are familiar with.

    It isn't clear if "Existing Images Optimization" will continue running in the background once you start it, or if you need to leave the page open. Navigating away from the page and returning seems to suggest it will.

    It would be great to have an additional message explaining this, like "You can navigate away from this page. The process will continue in the background".

    With all that said, this plugin is already far more than it was when we first installed it. We switched hosting providers a few times before landing on siteground a few months ago, and had some initial hiccups with SG Optimizer.

    It's great to see how far the plugin has come, and very reassuring that updates and features keep coming. Keep up the great work 🙂

    Here is what Thrive Themes says:
    "ALSO IMPORTANT! Because Thrive Architect is creating lines of code behind each action you take, it’s incredibly important that you disable minification for logged in users! Minification can clash with any plugin, not just ours!"

    Do you offer such an option to exclude minification for logged in users? When minification is "“is the process of removing all unnecessary characters from source code without changing its functionality”." and SG optimizer is shortening the code for logged in users, then it would destroy the whole website.

    In 3W total cache there is a switch where it is possible to turn off / on the optimization for logged in users. It would be fantastic, if you took care about this as well for all of us content builder users.

    (I'm using GoGeek plan)

    I've been reading a lot about SG Optimizer and also CloudFlare, but I'm a little confused and need your professional advice @Hristo.

    1: Is the free CouldFlare account enough for using it WooCommerce? Because I can't exclude the WooCommerce Pages pages with the free version.
    /wp-admin
    /wp-login.php
    /cart/*
    /my-account/*
    /checkout/*
    /contact/*

    2: You mentioned in here that it is possible and maybe a good idea to use both CloudFlare and SG Optimizer together with WooCommerce site. If I exclude URLs in SG optimizer would that also be excluded in CloudFlare?

    3: Is it a better idea to use ONLY SG Optimizer and NOT CloudFlare?

    4: If used both would that have negative effect on my WooCommerce site? I mean order pages cached, cart pages cached so not ideal.

    5: Does Cloudflare save orders made in WooCommerce?

    Thank you Hristo

    • Reply January 29, 2019 / 07:17 Hristo PandjarovSiteGround Team

      We have many customers using CloudFlare plus SG Optimizer. Actually, unless specified otherwise, CloudFlare will cache only your static content which means you don't need to do any exclusion of URLs whatsoever. For a standard installation you don't even need to do it on your WooCommerce store since the plugin has been designed to work with WooCommerce and will not cache the pages you've mentioned. CloudFlare is a CDN, if you have a local site, targeting your country, I would keep it off. On the other hand, if you're targeting more than one country with it, enabling CloudFlare is a great idea.

    This new version of the plugin is much better, thank you for developing it and maintain it.
    Regarding CSS and JS combining I understand your point about HTTP2, but sometimes combine some very small CSS and JS created by plugins could be really helpful, if you know what you are doing.
    Therefore, please consider to add this "advanced" feature in future to have more flexibility.
    In addition it happened that sometime minification break the functionality of some plugins, and it would be really nice have the possibility to granularity exclude some of them.

      In the upcoming version update we will provide additional functionality to combine CSS files and to defer JS scripts on separate options plus additional optimizations!

        Can't wait for the next version 🙂 An option to defer JS/CSS and combine CSS would be great! thank you for the great plugin.

    When I go to the cpanel I don't see this option for me in the Dynamic Cache? Is it because I have Cloudflair?

    I just installed this plugin and received the following error message: "Important warning from SG Optimizer plugin: We have detected that there is duplicate functionality with other plugins installed on your site: Really Simple SSL. Please note that having two plugins with the same functionality may actually decrease your site's performance and hurt your pages loading times so we recommend you to leave only one of the plugins active."

      Yes, duplicate functionality is bad. You can delete Really Simple SSL and force HTTPS using the SG Optimizer.

    Hello,
    I loved this plugin - it works much better than what I am currently using. However, it seemed like it didn't get along well with the Divi theme. Divi is fairly popular, specifically with those of us who aren't strong programmers.
    Thank you anyway.

      Plugin works fine with Divi, please post a ticket in your Help Desk if you're experiencing issues so we can look into it 🙂

    using latest version of your plugin and my experience has ben good. however, a few questions:

    1. i am using autoptime+async javascript. as such, i disabled all sg-optimizer frontend optimizations. do you recommend this setup or should i use ONLY sg-optimizer?

    2. currently, i have smush deactivated and sg-optimizer compressing my images. however, as of yesterday [even after purging all caches] it seems as if sg-uptimizer is never going to finish optimizing my site's images. it's been 2 days now.... any thoughts?

    best,

    • Reply February 18, 2019 / 02:14 Hristo PandjarovSiteGround Team

      In the upcoming update 5.1 we will introduce Async JS load and CSS combination so you won't need any other plugin! As for the image optimization, please check if you have your WordPress cron enabled. It's designed to work slow but steady in order to avoid extensive resources usage. If it's on, please post a ticket in your Help Desk, so we can look into it.

    Hi Hristo, great job done with the SGOptimizer including image optimization and the rest of new features!

    Is already supporting WebP format for high WPO like shortpixel does? If not do you have an estimaed date for this release?

    I have a GOGeek account, but some customers of mine are using GRowBig or even StartUp accounts. Is there a comparative table with which features of SGOptimizer are available in every product?

    Also, Is Elementor and elementor Pro fully supported?

    Thx in advance

    • Reply February 19, 2019 / 01:32 Hristo PandjarovSiteGround Team

      We're launching 5.1 with CSS Combination, JS Async load and WooCommerce support for Lazy Load features. WebP requires additional updates on some systems and we've planned to add it in the upcoming updates. It's on the roadmap but won't get into the next release. The Optimizer works on StartUp too, they just don't get the dynamic cache. Thinking in that direction too. As for your other question, yes, Elementor is fully supported.

    Hi Hristo, My hosting is with SG and I've been told I need to use your optimiser. I have several websites but one is very image heavy and is loading really slowly. I cannot use the 7+PHP because my theme doesn't support those. I used to use Imsanity along with some other optimiser plugins but now only SG optimiser. Can I reinstall imsanity or anything else to get my site working faster again? - it went wrong recently when some change at the SG end was made and I had to change the PHP settings in Cpanel as a result. But now it is really slow and that is a disaster.

      It seems you're duplicating functionality. Could you make me an admin account with hristo.p [at] siteground.com and shoot me an email. I will look into your site and make sure you're getting the best speed out of your theme.

    Hi Hristo,

    Thanks so much for this great update and all the information - you have been very generous with your time providing answers to everybody.

    I would kindly ask that you update your documentation and PDF guide to reflect these new updates. I was not aware of these updates and was using your documentation and PDF guide and so suggested that my client purchase shortPixel and was about to embark on the long journey of the 21 steps when this update does most of this automatically.

    Thanks,

    Hi Hristo, Please advise. I enabled all Lazy Load Images on SG Optimizer, but still Google PageSpeed Insights showing error "Defer offscreen images - Consider lazy-loading offscreen and hidden images..."
    Please advise why still I am getting this error of Lazy Load Images?

    • Reply March 26, 2019 / 04:43 Hristo PandjarovSiteGround Team

      You need to look into your Google PageSpeed report and examine the exact issues reported. Images can be rendered by different ways, the test might be reporting false positives, etc.

      • March 29, 2019 / 18:39 Daniel BrownSiteGround Team

        Thank for your reply. I check / test again the site on Google PageSpeed and I see that the error "Defer offscreen images..." appearing only on mobile test. On desktop NO error. It's can be that Lazy Load Images of SG Optimizer, only working for desktop and not for mobile? Please advise.

        Hi Daniel,
        Please submit a ticket for this issue so we can investigate in more details the outcome you are seeing. We can also suggest you check the forum of the plugin for discussions on this topic and other users' input about it.

    Recently, our site started to get "504 Gateway Timeout" error messages on the backend when logging in. When "memcached" was disabled in the SG Optimizer plugin the problem went away.

    Apparently memcache was using too much memory for normal processing of other processes to complete in the 120 second default server timeout delay. Why memcache should create this problem is unclear as a feature that is supposed to speed up delivery is in fact slowing it down. Perhaps there is an incompatibility with another plugin but I do not know how to debug this problem properly. In any case memcache seems incompatible with our site at present. Any ideas?

    • Reply May 27, 2019 / 07:50 Hristo PandjarovSiteGround Team

      That's how Memcached works, if the size of the slab is too big than the memory pool it has available you will get the issue you've described. I would recommend to upgrade on a Cloud account and request our team to configure Memcached as per the needs of your site. It seems that it needs more memory for the Memcached service.

    great plugin.
    How to cache SEA landing pages?
    Each user arrives with a unique gclid parameter.
    So each URL ist "new" and doesn't hit the cache.
    How to cut off the query params?

      I am afraid that at this point we don't support that. It's on the roadmap though and we will be able to exclude global parameteres like the ones for Google ads and Facebook.

    We are getting an error notification from SiteGround that our current W3 Total Cache WordPress plugins are not compatible with PHP 7.1 and we are thinking of pivoting to the SG Optimizer. Is the plugin comparable?

    We are helping an orphan client that no longer speaks with their web designer? We are hopeful that the switch will not cause dramatic issues with the site. Our plan is to make a backup, deactivate W3, and then make the conversion. Would this be the best course of action in your opinion?

    • Reply July 17, 2019 / 05:32 Hristo PandjarovSiteGround Team

      You can update to 7.1 safely. We will add W3TC to the exclude list. That aside, I would recommend switching completely to SG Optimizer since it now provides everything you need to optimize your site for best performance.

        I noticed that WPEngine has a manual way to support webp by manually creating another file with the same name in the same WP directory and then asking support to create a NGINX rule to pick the webp version if it is compatible with the requesting browser. See article at https://wpengine.com/support/webp-image-optimization/ . I use both WPE and SG. Love them both.

      • September 11, 2019 / 05:48 Angelina MichevaSiteGround Team

        Hello Charlie,

        Thanks for sharing this. We're glad to hear you are happy with our services. Regarding webp we wanted to let you know we're working on that for the SG Optimizer and it's in our plans to include it in future releases.

      • September 11, 2019 / 06:32 Charlie SasserSiteGround Team

        @angelina | On an individual account can SG create a NGINX rule if we manually create a .webp version of the image in exactly the same WP directory with say the exact name as a png file like example.png and example.png.webp so the rule will pick the .webp version if the client browser supports .webp?

      • September 11, 2019 / 07:56 Angelina MichevaSiteGround Team

        At the moment it will not be possible to do that on your SiteGround account. Instead, you can add htaccess rules to check whether there is .webp version of the image and use it in the place of the generic file. As mentioned previously we aim to include this in future releases of the plugin and thus make it available for our customers.

    Has there been any testing to determine if SG Image optimization works better / worse / same as Imagify, Smush, and others. I like the idea of consolidation but only if there's a benefit. if there's no testing done, can you elaborate on the different processes used so we know SG method vs Imagify/Smush/etc.

    • Reply August 22, 2019 / 04:45 Hristo PandjarovSiteGround Team

      We've selected what we believe are the best optimization services and use them in the most efficient way. I havent tested against other free and paid services but image optimization is pretty much established technology and there isn't anything that the above mentioned plugins can do signifficantly better.

    Hi,

    Just a few more questions:

    1) Were you able to run your comparisons on your Image Optimization feature vs ShortPixel or Cloudflare's Polish and/or others?

    2) Do you have a pre-test feature to see what an image looks like before/after optimization?

    3) After Optimizing prior images, does your plugin generate a report of pre/post image sizes? Even an overall total of MB before and MB after would be interesting.

    Thanks!

    • Reply November 8, 2019 / 03:45 Hristo PandjarovSiteGround Team

      I am afraid the answer is no to all the questions. However, we're working in that section and soon there will be a lot of updates regarding image optimization!
