How to troubleshoot WordPress blank page?

In the majority of the time a "white screen of death" can occur if a certain plugin is not functioning properly. It could also be caused by a poorly coded theme that your website is using. Since there might be multiple reasons behind this blank page we would recommend you to go through the steps below:

  • Disable all plugins

You can deactivate your website plugins via FTP. Navigate to the WordPress plugins folder on your hosting account:

/path_to_your_application/wp-content/plugins

and rename it (e.g. to plugins.back) so you can deactivate your plugins temporary. After that you can test your website.

If the website starts working correctly this means that one or more of your plugins are causing the issue. In order to fix it rename the plugins folder from plugins.back/ to plugins/ and open the folder itself. Once you are within this directory you should move one by one the subfolders of each plugin out of the plugins/ folder - then test your application. If the issue is resolved this means that the plugin that you have moved out has been causing all the troubles.

After the problematic plugin is found check whether it is compatible with your version of WordPress. If you plan to use it contact the plugin's developers and report the issue.

  • Replace your website theme

You can switch your website theme to a default one like twentyseventeen in order to check if your theme is causing the blank page issue. Simply access your cPanel, go to phpMyAdmin and navigate to your WordPress database on the left side. Select the wp_options table and update the following values:

template and stylesheet to twentyseventeen for example.

You can again test your website and verify if the issue is resolved.

  • Increasing PHP resources

Depending on your WordPress setup your website might require higher PHP server resources. You can increase the value of memory_limit and enable output_buffering at your host in order to verify if this was causing the issue.

If you are a SiteGround customer you can do that from your cPanel, under PHP Variables Manager.
