vB 4.0.3: Always use Forum URL as Base Path
There is a conflict with the vBulletin 4.0.3 settings "Always use Forum URL as Base Path". If the board URL is not the same as the wiki URL, or is anything deeper than the domain root, wiki pages will load / redirect infinitely.
If you're using 4.0.3 and VaultWiki together, keep this setting disabled until RC 2 is released.
