I've installed this mod.

Its designed for 3.0 but it works on 3.5 except for 1 issue. vBulletin thinks someone is trying to access a NON-permitted vBulletin file/page. Since basically the only pages allowed to be viewed are pages like showthread, forumdisplay.php and the few others.
But this mod creates redirect.php and I don't know how to give FULL permission irregardless of logged in or out to allow vBulletin to make this page viewable without permission issues.
