Hi, we just upgraded from 2.62.00 to 2.96.00 in order to correct an issue with processing payments through Authorize.Net. However, we still can't get a transaction to go through. We get the following error when using a real card, Authorize.Net NOT in TEST MODE and the cart NOT in "Test" mode.
We couldn't complete your payment.
Status : False
Message : The Global Payment System identification numbers are incorrect. Call Merchant Service Provider.
What do you suggest we do? We need to get this system working ASAP.
Thanks in advance for your help!
