I'm reading the maual and I see that if you want to Ruby, Perl and Python available you have to install additional mod installs. I installed my server with the how to https://www.howtoforge.com/perfect-...2-php-mysql-pureftpd-bind-dovecot-ispconfig-3 So are they installed or do I need to install this mods and how to install them?
Ruby and python get installed. Not sure if mode_perl is installed, if it is missing, install it with apt.
