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 can access the server but I there is nothing there. When I tried the perl example. I got an error that I the file doesn't exist. I toyed with the conf files and now I 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?
