I don't know if this has been addressed yet, and I can't spend 1/2 a hour to a hour reading through 30 pages of posts to see if it has been.
I have custom user groups in my forums for VIP, Donator, etc etc. They can login ok to the forum itself, but get a permission error messages when they go to the main site which is a vbindex (renamed index.php) page.
Please help kind sir, this is an awesome hack for vbulletin indeed! I have not upgraded to 2.2.7 because I'm afraid I'll lose all the customizations I made to the board.
