Ok got it installed backend seems to work but when I got to the URL I get:
Fatal error: Call to a member function on a non-object in /home/stuntusa/public_html/forums/vBChat.php on line 224
You can also see the error here

I must have missed something simple as I have installed lots of mods, any ideas what I might have missed?
