0 Event Registration Page stalls on loading Payment Page. 1 Morgan Woods-Leshe posted 7 Years Ago We have been getting a lot of people from different browser types and mobile/desktop saying that some of our event registrations will stall out with the little thinking bubble when they click to get to the last payment page. It then throws this error. We get a few of these a day. Any ideas?An exception has occurred.
