Hi all. I'm set up on version 1.3.6. I have my own SSL and certificate, both installed and operational.

Visa and Mastercard are both enabled in Configuration>Credit Cards

When I use the ZenCart basic cc module, everything works fine.

When I try using the goemerchant payment module (downloaded from here), I get the following error when I try to process:

payment_error=goemerchant&error=The+credit+card+number+starting+with
++was+not+entered+correctly%2C+or+we+do+not+accept+that+
kind+of+card.+Please+try+again+or+use+another+credit+card.

Looking in the faq here, I see that that's normally an error message one gets when the credit cards are not enabled in Configuration>Credit Cards, but mine *are* configured. I get the same message in both Test and Production mode, with test and real credit card numbers.

Any clues? Or is this something solely on goemerchant's end? Thanks!
