Can't log out from "message boards" (bbs) page

The logout button on the vimm.net/bbs page doesn't seem to work. When clicked it redirects to vimm.net/logout.php giving a "File not Fount" error. All the individual message boards have functioning logout buttons, and signing in isn't a problem anywhere. Hope this can help fix the issue! :D "Learning to fly is learning how to throw yourself at the ground and miss."
