I just upgraded my site to vBulletin 3.7.x this weekend and I have the same error.
You can see it here:
Main Index - My Photo Gallery
Login: (USER ACCOUNT REMOVED NOW)
Password: (password removed now)
For some reason after you log in it does not redirect to the photoserver (trying to figure that one out too) but when you return to the page you see the error...
Warning: mysql_fetch_row(): supplied argument is not a valid MySQL result resource in /home/MYACCOUNT/public_html/photopost/pp-inc.php on line 4214
---- some notes as I work on this...
- Same in IE and FireFox
- The Blue box below Navbar shows a REGISTER link so I assume user is not logged into Photopost
- Admin Account does not see this at all!
- Went to [Edit Usergroups] and clicked [(Refresh usergroups from your forum software?)] to no benifit.
--------------------------------------
OK, I figured out my problem, perhaps it will help someone else!
When I upgraded I did so to a new database and I forgot to update the config settings in PP to point to the NEW forums database! As soon as I updated this and re-ran the REFRESH usergroups option the error went away!
