When I post a transaction in PS test mode it works fine. When I take PS out of test mode and Authorize.net in testmode it fails with a message
Your transaction could not be completed. Either your credit card information or billing address has problems and cannot be processed
Please return to checkout and try again."
I have the diagnostic code in place that you provided and the results are attached.
Can you tell me what is wrong.
As you can see I used the Authorize.net dummy CC numbers etc but I get the same results if I take Authorize.net out of test mode and attempt to run a live transaction.
I have tested from Authorize.net to our merchant gateway and that does work. It appears to be something between PS and Authorize.net.
The Authorize.net folks don't even see the transaction. The did tell me that the URL that PS should post to is transact.dll if that helps at all.
your help is appreciated.
