Does WP-Ecommerce allow you to test with an authorize.net sandbox account because I am getting: "The merchant login ID or password is invalid or the account is inactive."?
I have created a sandbox account and have entered in my api and transaction key into the WP settings, but it is not working. I've tried it with test mode checked and unchecked.
