when reload PHP-FPM 7.2  in PHP-FPM Selector  get this noice =>  Reload service php-fpm warning, no pid file found - php-fpm is not running ?

any suggestions?? please help

It seems that because of using the php-fpm selctor
And because it's not for free, then the php is disabled and locked for users!!!

But What can I do now to disable the php-fpm and be able to use cwp???

At the moment our sites are giving error 503

you need to uncheck force php-fpm and use php-cgi

Can you share steps by steps how to do that? I tried but didn't get it to work.
