WordPress MU

Hey everyone,
It looks like this error is popping up on the top of some of my pages

WordPress database error: [You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '' at line 1]
select count(cid) from

Everything still works fine, it's just an annoying eyesore, so any idea hwo to get rid of it?

Thanks!

I hope that isn't a production site with errors being displayed to the screen.
