Hi, I just installed Ispconfig on new server because I tought to migrate from apache to nginx. Everything works fine but I can't see Fast-CGI option for my site, there is only PHP-FPM. I am using Ubuntu 20.04 and php7.4. Thank you
Nginx does not use the old FastCGI mode. On Apache, you should not use it anymore as well. FastCGI is the predecessor of php-fpm and exists on Apache systems just for legacy reasons, you won't use it anymore today on new systems or when creating new websites.
