[Support request] 404 Error when payment made

Customers are placing their order via credit card. Once they click the captcha field and OOK, the purchase goes through via Stripe. The issue that alarms users is that once they click the button, as well as the payment going through they get a large red “OOPS 404” error msg splashed across screen. Some then panic thinking the payment did not go through, and process the payment again only to get the 404 msg again as well as paying twice.
