Hello! We had folks that wanted to pay at the door and there was no way to go back and allow them through your your system to use the paypal. So once they were in the system you could not go in and move them from pay at the door to pay by credit card. It would require removing them from the event and reregistration them. I ended up creating a simplified onsite new event but it would be nice to adjust on the real event so that records are correct.
