Had a client attempt to purchase a t-shirt from my WordPress blog using the Eshop Plugin. Have used your plugin previously with authorize.net and it worked fine, but the transaction from Friday 11-9-12 is not processing. I've set up a help desk ticket with authorize.net and they have identified the plugin as the problem. I'm getting the following error and need your help resolving please "General Error Processor error - The merchant account is not configured properly with the Credit Card Processor. Contact merchant service provider for resolution."
Thanks in advance for your help! Blase
