Anyone have any experience with this type of error message? Since the validation in the checkout process prevents customers from entering a credit card number that is not of the same type as the credit card they had previously selected I am at a total loss as to what this could indicate.
On the front end, customer transactions that trigger this code redirect users back to a still-full shopping cart instead of to the “thank you” page. Payments are still processed through PayPal in normal fashion. Problem is intermittent (but increasing in frequency) and occurs with multiple credit card types (so far both Visa and Amex) and with customers from different states.
Since this error started presenting itself orders have gone from +/- 50 per week to just 9 last week. Might not be related but I don’t want to take any chances.
I’m out of ideas so any help, comments, etc… would be sincerely appreciated.
