Hi, just realised this after reading this thread.
I have a subdomain forums.mysite.com which I've created from the Cpanel (which created the forums folder; in the public_html folder as well).
However, as the forums folder is in the public_html folder, thus users are able to acces the subdomain by typing in mysite.com/forums, which I do not want but rather want them to access it via the subdomain, forums.mysite.com. Is there a way to disable the access by the mysite.com/forums way?
