[SELECT count(*) as count FROM subscribers WHERE email_address = '[email protected]']

I get this following error EVERY TIME someone tries to confirm their order and return from paypal to the store. This also means that orders doesn't register which is a huge problem for us and we have no explanation or an idea how to fix it. What could I do.. I didn't have this problem before.. it started with our new store and fresh install of the new zen.
