296792 Unpaidcash IPN fix for Paypal

Hello, I have this IPN setup with my account at paypal as well as clickbank. I need help with the paypal one. First off I need this IPN to instantly update mydb with the username and password it creates... What seems to happen is that it works great..generating the username and password. But then they dont work! It seems paypal should be updating my mySQL db and i see nothing. The IPN is setup for [login to view URL] This need to update instantly. Also i would like you to test the clickbank. When i try to pay for clickbank..i get this error: Database error: Invalid SQL: INSERT INTO members (subscr_id, username, pword, active, joined) VALUES ('XE2098F0','',ENCRYPT('07118fa7'),'y',NOW()) MySQL Error: 1062 (Duplicate entry '' for key 2) Session halted. This needs to be fixed. And last thing is I need a way to just throw out a standard username and pass that will always work. Basically tell me what to do if I want to do this. Kevin
