My customer received an error saying that her address does not match the billing address and her transactions never went through or so it seemed. She used a Visa and was charged twice through Paypal but these transactions did not go into Zen Cart. I checked my logs and I didn't see the error in any of the files. I checked my E-mail Archive Manager and found this error twice. ALERT: PayPal Direct Payment Error ( _!-- --_) There is no description for the error. What can I do to fix this immediately? I don't want my customers to be charged multiple times especially when I can't see why. I have the setting for "confirmed address" set to off. What else do I need to do? Thanks!
