Hello, I have last Ispconfig and Debian 12 installed with automatic script. I switched to PHP-FPM for debugging and now I can not revert to Fast-CGI. No option available: Why? Regards, L.
Was Fast-CGI available previously? My understanding is that Fast-CGI is old technology, new systems should use PHP-FPM only. https://forum.howtoforge.com/threads/fast-cgi-vs-php-fpm.84263/#post-402423 If you really need fastcgi and are running Apache, this tutorial shows how to install fastcgi mode for PHP. https://www.howtoforge.com/ispconfig-php-debian/
Fast-scgi is the predecessor of php-fpm, so fast-cgi should not be used anymore today. Why do you want to use that old PHP mode instead of the php-pm mode? Besides that, you can re-enable the old fast-cgi mode under System > interface config, but it's not recommended to do so, and deprecated PHP modes like fast-cgi will get removed sooner or later anyway. better use php-fpm instead.
