Stripe Checkout - There has been an error processing your credit card

[Guest]

Dear All,

I'm getting an error with Stripe Checkout. It says;

There has been an error processing your credit card

Please try again and if problems persist, please try another payment method.

Here is the debug email that I've received;

$HTTP_POST_VARS:

Array
(
    [matc] => on
)

Your help would be greatly appreciated.
