Greetings, I've had comments over the years from registrants who are confused by PayPal. They think if the payment method says "PayPal" that they need a PayPal account. I've done custom overrides to say "credit or debit card processed by PayPal," and added a custom graphic that shows 4 credit card types with the PayPal graphic more in proportion to the rest. This seems to have helped.
The problem is that I have to re-upload the graphic again every time DTRegister updates.
