I'm trying to get this PayPal IPN tutorial to work: http://net.tutsplus.com/tutorials/php/using-paypals-instant-payment-notification-with-php
I setup everthing and now I'm in the PayPal sandbox and sending with the "Instant Payment Notification (IPN) simulator" a message to my "ipn.php" and nothing happends. The databse is still empty and I don't get a notification email.
I'm totally stuck with this. What can I do to find the error? Thanks Michael
