The files do not exist/not accessible. I even created a shareit login in order to see if this was the problem for accessing the PHP file. I've got a thread that is related to this (TestLink in subject) as I am trying to find a way to access GTA Service Desk for the Problem page (either to link to an existing problem or post a new problem from a test failure).
So if anyone has the php source, I'd love to look it over to see if it could work for my needs (TestLink).
