Official PayPal IPN Support Thread in Other Posted December 25, 2006 Have you tried replicating the problem with other payment modules? Good point. You're right, I have no reason to believe the problem has anything to do with the PayPal IPN module. I just thought it would be worthwhile to see if someone chimed in and said "Yes, that's exactly what happened to me--and here's what the problem is." Since no one has done that, I guess I have to get to work. :'( Thanks for the suggestion. I'll try some stuff to isolate the source of the problem.
