Issue: Conflict with another plugin

Hi Ted, I bought provb's 'Answer Forums' unbranded version for $50 from http://www.provb.org/vb_products.php...o&productid=10

It is a simple question & answer script for vbulletin (activated per forum) of course I only wanted it for one forum called Q&A About Lamps...

...but I have shut it off for now because when making a post in the activated Q&A forum I get the following wiki code error, though the post seems to go though , but I have to approve it.

The only thing set to approve for regular members is the wiki. Otherwise members can post anywhere with no mod que, so it leads me to think it does have something to do with the wiki.

Fatal error: Cannot redeclare handle_bbcode_bracket() (previously declared in /home/tvlamp/public_html/includes/class_bbcode.php(2463) : eval()'d code:236) in /home/tvlamp/public_html/vault/special_class_bbcode.php(3613) : eval()'d code on line 254

Of course I have no idea if vault wiki is causing it or the Anser Forums script (it only happens in the one forum that I have the answers activate)
