MultiPHP INI Editor not working with Mod_LSAPI

Symptoms

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

Cause 

When using the Mod_LSAPI PHP handler, the default configuration does not read local user INI files. 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 this interface's functionality, you will need to modify LSAPI's default configurations. 

Resolution

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.

   CONFIG_TEXT: lsapi_enable_user_ini On

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

   CONFIG_TEXT: lsapi_user_ini_homedir On

5. Save the changes and exit the text editor.

6. Restart the Apache service.
