I am using a Magento 1 of version 126.96.36.199. Recently i update a patch for Authorize.net and right after that i started getting issues. Currently in the site with live Authorize.net credentials if a admin creates an order and tries to save it, the system redirects the admin to front-end shopping cart page but the order is getting created successfully.
This is happening only with Authorize.net.
I have tried replicating the same with the sandbox credentials but when it try to create a order i get a error message as
An error occurred while trying to report this transaction to the merchant. An e-mail has been sent to the merchant informing them of the error. The following is the result of the attempt to charge your credit card. This transaction has been approved. It is advisable for you to contact the merchant to verify that you will receive the product or service.
But the order is getting created. I am not sure what causing the system to redirect to front-end. I didn't find and information from the logs as well.
If anyone have faced a similar issue please provide the solutions or any approach to find the issue.
