Issue: IE JS Error on No Permission

Okay, here's another IE JS issue. When viewing showwiki.php and receiving a vBulletin error instead of the desired page (e.g. no permission error or invalid id), Internet Explorer will say that vB_Section is not defined. Apparently, VaultWiki is still setting up some JavaScript for posts even though none have been served. This should only happen with errors on showwiki.php because VaultWiki expects the parent JS file includes to be hardcoded to the vault_article_main template and they are not added dynamically as with other pages.

In Internet Explorer this prevents tabs from being served if a no permission error occurs. This doesn't make too much sense but should be possible if a user is logged out because of a cookie timeout.
