Click Apply. The system will change the selected domain's PHP version.
The system displays a PHP-FPM enabled (✓) or disabled (×) indicator in the PHP-FPM column for each domain. System administrators can enable or disable PHP-FPM through WHM's MultiPHP Manager interface (Home >> Software >> MultiPHP Manager).
- When you change the PHP version of your domain and FPM is enabled, the system changes your FPM version to match the PHP version. If FPM is not enabled on your domain, the system changes the PHP and FPM versions separately.
