MultiPHP INI Editor not working with Mod_LSAPI

Symptoms

When updating PHP settings through the cPanel MultiPHP INI Editor interface, the changes are not applied to the domain's PHP environment. 

Description 

When using the Mod_LSAPI PHP handler, the default configurations provided do not read local user INI configurations. As a result, switching your PHP handler to the CloudLinux-provided Mod_LSAPI will prevent the MultiPHP INI Editor from working as expected. To restore the functionality of this interface, you will need to modify the default configurations for LSAPI. 

Workaround

1. Access the server's command line as the 'root' user via SSH or "Terminal" in WHM.
2. Open /etc/apache2/conf.d/lsapi.conf in your preferred text editor.
3. Remove the # from the lsapi_enable_user_ini line and change the value to On.

   lsapi_enable_user_ini On

4. Remove the # from the lsapi_user_ini_homedir line and change the value to On.

   lsapi_user_ini_homedir On

5. Save the changes and exit the text editor.
6. Restart the Apache service.
