I set up a system with this module to let users purchase credits with paypal standard. After checkout, a product that should give 10 credits is giving two 10 credit = 20 credits. I adjust credits and it always rewards double. I am also getting double e-mails receipts for this purchase. I think it has something to do with paypay because when I initiate payment, it makes one credit entry. When I press return to merchant on paypal, it makes another entry and the second e-mail. I see some other people are having double transactions with ubercart with different modules too. I reinstalled a few times and always does the same thing. Please Help!
