Additional PHP settings are not updated in phpinfo() page for a Plesk hosted domain on CloudLinux server

Symptoms

• Additional and/or custom PHP settings at Domains > example.com > PHP Settings are not applied to the domain. e.g. memory_limit.

• Going to Domains > example.com > PHP Settings > View the phpinfo() page > The phpinfo() page shows that the Loaded Configuration File is a server-wide PHP configuration file:

  • OS PHP: /etc/php.ini

  • If Plesk PHP is used: /opt/plesk/php/X.X/etc/php.ini

    * Where X.X is the PHP version, for example: /opt/plesk/php/7.2/etc/php.ini

• Plesk is installed on a CloudLinux OS server.

• Going to LVE Manager > Selector tab (It might be necessary to click on the icon ) > this is found set to Native.

• CageFS is installed and enabled for the domain subscription's user :

  # cagefsctl --user-status johndoe
  Enabled

Cause

CageFS restricts the domain system user to use the server-wide PHP configuration not allowing any additional or custom setting.

Resolution

Note: In case CageFS is needed to be enabled for the system user, contact CloudLinux Support Team to get recommendations on its configuration.

  1. Log in to Plesk GUI

  2. Go to Extensions > My Extensions > CageFS > Find and select the enabled system user > Click on << to disable CageFS for the user:

  

  Via SSH

  1. Connect to the server via SSH

  2. Disable CageFS for the Plesk subscription's user:
