When I tried to upgrade my account from Free to Basic using the credit card option I received this error:
PayPal Server Error: The credit card type is not supported. 10566. Credit card type unsupported
I don’t quite understand this error as I was making the payment with a Discover card. Considering that this is an option from the drop down menu I assume this is a valid method of payment. I suppose I can make the payment from my PayPal account but it’s going to take a few days to get verified.
