Adding Braintree payment module

[marton_1]

When the form data is submitted to your server, the payment module takes the card number and passes it to the cc_validation class to be sure that it matches the card types that you've configured your store to accept in Admin->Configuration->Credit Cards.

But, since the error message you quoted isn't showing *any* of the rejected digits, it's possible that the value is blank when being submitted.

Or, it could be that the translation logic in your language files is missing the placeholder that displays the card number. (First test for that is to switch to english and see if the same message also doesn't show the digits.)

Thanks for your reply.
I switched to English but there are still no digits shown in the error message for Mastercard.

Visa card payments work correctly.
