I have been having this problem intermittently. It's only happened a few times, but I have no idea why it's happening. I received payments via PayPal, and I get the notification of payment from PayPal, but there is no order showing up in Zen Cart for the purchase. I have been issuing the customers gift certificates for the amount and having them go back in and place a second order as a work around. Still, I would like to know why it's happening to start with, and why it only happens occasionally, not with every order. I am using 1.3.0.2.
