Ok, I tried that out. The first one did indeed echo, but the second one didn't. So this means I need to go into the php.ini config file and change something? I can't seem to find this php.ini. Should I be looking somewhere?
Edit: It works now! Before in my plugin I was putting the entire path in (
http://www.yoursite.com/forum/test.php). So I just changed it to "../forum/test.php" and it works! So it must be a problem with the php.ini. I looked around and it sounds like it is a real huge pain to mess with. Unless it is simple, I will just remember to not put the full path in.
