I've followed this tutorial to try and set an apache server: http://www.ubuntugeek.com/how-to-install-apache2-webserver-with-phpcgi-and-perl-support-in-ubuntu-server.html/comment-page-1#comments
At first I got a message that I could access the server but there was nothing. When I tried the Perl example, I got an error saying that the file didn't exist. I toyed with the conf files and now can't access the server at all. When I type the address of the server I get a forbidden message.
How can I step back my changes? How can I create the cgi server?
