hmmmm.... The exclude is definitely still there- maybe you just manually modified the link to add the "&exclude=..." to the URL in the template- that's what I do and the "official" answer if you ever searched vb.com...
In any case the error doesn't have to do with the URL but that the SQL sever can't be found, in this case: sqlc6.megasqlservers.com -that's damn weird because it's obviously the rest of the site is running fine and the sql server is the same throughout... I'd say maybe a mod is messing things up... Turn off your hooks and see if you still have the problem.
