http://forums.lnlpublishing.com works but when you visit a thread you get a 505 error.
GD is installed. I did use the script: http://forums.lnlpublishing.com/xenforo.php
It also give me http://forums.lnlpublishing.com/login/login when I try to sign in.
I do not recall if "forums" was on the end or not, just as an FYI.
