Alex, Our developer Dan upgraded our 4.x to 4.2.6 the other evening. Then the next day several payments came in with one being a coupon. It had an error message but it incremented the next month of classes for the student. Today another coupon student payment came in and it "didn't" open up the next month of classes --- the error message said it didn't recognize the IPN. We were working just fine before the upgrade --- now we are in a serious situation with this situation. Can you log into our system and fix this problem. Sincerely, CindyThanks for contacting us Your message has been received! We will respond to you as soon as possible. Your reference number is: #IPS-39713-949
Alex, Apparently there is a patch fix that you had given Dan when this happened with the 3.x to 4.x upgrade. If you could supply us with this patch again he can implement and resolve the problem. This information of which I speak is in my ticket history.
