If you're encountering an issue where an invalid php.ini is being used for lap domains in Plesk, it could be due to various reasons. Here are steps you can take to troubleshoot and potentially resolve the issue:

1. Check PHP Versions:

   Verify that you have the correct PHP versions installed and enabled for Lap in Plesk.

2. Check PHP Settings in Plesk:

   • Log in to Plesk.
   • Go to "Domains" and select the affected domain.
   • Under "PHP Settings," ensure the correct PHP version is selected.

3. Check php.ini Files:

   • Make sure that there are no conflicting php.ini files present. Check for any custom php.ini files in the domain's document root or subdirectories.

4. Verify CageFS Configuration:

   If you're using CageFS, check if it's causing any restrictions on php.ini files. You may need to update CageFS configurations.

5. Check Permissions:

   Ensure that the php.ini file and its parent directories have the correct permissions and ownership. It should be readable by the web server process.

   bash

• chmod 644 /path/to/php.ini

• Review Mod_lsapi Configuration:

  Verify that mod_lsapi is correctly configured in Apache. Check if there are any directives that might be overriding the php.ini settings.

• Check for Custom PHP Handlers:

  If you've set up custom PHP handlers, make sure they are configured correctly and do not conflict with Lap.

• Restart Apache:

  After making any changes to the configuration, restart Apache to apply the settings:

  bash
• systemctl restart apache2

• Verify phpinfo():

  Create a simple PHP file with the following content:
