error when accessing categories / products in admin

1146 - Table 'xxxxxx_vbulletin2.TABLE_USER_GROUP' doesn't exist

select usergroupid, title from TABLE_USER_GROUP order by usergroupid

This is the first time I've seen this. I also get this when I try to access the product attributes, manufacturers.

Any ideas?

Thanks!

Sorry about that.

Problem was caused due to an error in an addon.

no problem and thanks for the fix and your support!
