1 month ago I setup 3 payment buttons in my sandbox account, every button with a different IPN page.
Everything worked ok then. Now when I wanted to test again, I didn't received any ipn message. The page is not called.
Going in my paypal account on Instant Payment Notification (IPN) history page I see that all messages are queued, but not sent.
Is this a bug from paypal? did they changed something in the last month and I need to modyfy?
