We're using the built in Authorize.net payment method on Magento 1.9.1.0. We have multiple domains in use. On the frontend orders are placed with no issues, but on the admin area the response isn't rendered due to a domain mismatch. The issue is when you try to place an order in the admin area for the 'domain1.com' website when accessing the admin via the url for 'domain2.com'.
Would anybody know of a way of resolving this?
