Ok so I changed the portal.php to index.php i followed this http://community.mybb.com/archive/index....-1268.html
and It works now how do I change the Link names like Forum Home, Member List, Search and stuff on the home page
and i'm getting weird errors when i post something in the forums too heres the error:

Reupload a fresh copy of class_parser.php

Have you added any custom MyCodes?? Either manually or via a plugin.
