Authorize.net authentication error help
I have setup the payment gateway for Authorize.net and when you enter the CC information and press "Next" the page reloads with "?error=" at the end of the URL. I can't find an error in the logs to see what the appropriate Response Code is to diagnose the problem; and no code is generated on the page. Also, the default error message "This transaction could not be completed at this time. Please try again later." is not displaying. I am at a loss. I need to get this up for the client, but can't proceed without having the CC option for payment.
I've setup lots of Ecommerce sites and never had this happen. I am willing to pay for a solution because I need the fix soon. Any help would be greatly appreciated.
