The 404 error page from the website root just displays a white page. This should display some sort of error or redirect really. E.g:
http://www.ownedcore.com/forum
http://www.ownedcore.com/test
http://www.ownedcore.com/forumtest
The redirect is fine on the forums subdirectory, e.g:
http://www.ownedcore.com/forums/testing
