The Softaculous developers regularly release new versions of the applications that can be configured via the auto installer. When you access Softaculous you will see the home page if there are any updates for your installed applications you will see a note on the top of the page.
You can click on the note and you will be taken to a new page on which Softaculous will list all outdated software.
On the new page you will see all outdated applications. There are several columns that provide important information about the outdated software. In the Version column you will see the current version of your script and a blue color Upgrade button which you need to click on to perform the upgrade.
You will see the next page from the upgrade process. Here you have an option to create a backup of the application prior to upgrading which is highly recommended. To perform the upgrade click on the Upgrade button.
Once the upgrade completes you will see a confirmation page.
