I'm having a problem getting the coupon codes to work on my site. I just upgraded to 1.3.5 and now it seems like one of my codes is not working.
The problem is when someone enters in the coupon code and then pays the balance with a credit card. The payment method (in the admin) says "Gift Certificate/Coupon) and the charge never gets processed by my merchant account. However, when a different code is used and the user pays via PayPal, it works. Any ideas as to what is wrong?
The only real differences between the coupons is that I have one (the one not working) set up as a "one use per customer", but that shouldn't make a difference.
