CMS "View All" doesn't work
 

I have several articles posting in the homepage of the CMS. Everything is great, except for the fact that the VIEW ALL feature doesn't work. Upon clicked, it gives me this message:

Fatal error: Call to a member function query_first() on a non-object in /home/..../public_html/discussion/packages/vbcms/controller/list.php(97) : eval()'d code on line 2

Last but not least, the CATEGORY feature also doesn't work. It's giving me a similar statement. Talk to the hosting guy, he told me it's a Vbulletin issue, citing a source here saying that there is a problem w/ VB regarding the CMS and the forum.

Any idea?
