Gateway Configuration Error
I am using the Authorize.net plugin with Vantage.
I have entered the API login ID and the transaction key and verified with Authorize.net that these are correct. I try to do a transaction and I get:
Gateway Configuration Error
I note a couple other people are getting the same error and I can't see that you have solved any of those issues.
My client is in a hurry to get this site up and running so I hope you answer. I am willing to send you my login details for the
WP site.
