I'm using STS, and tried this, but I'm still getting an error. It appears that the credit card number and info is not being validated.
Warning: str_repeat() [function.str-repeat]: Second argument has to be greater than or equal to 0 in /catalog/includes/modules/payment/cc.php on line 168
Processing Order, Please Wait...
It still processes the order, but doesn't perform any validation on the CC number, nor does it provide the type of card used in the orders admin screen
Has anyone else encountered this?
