We have followed all instructions provided by Authorizenet from this link:
http://community.developer.authorize.net/t5/The-Authorize-Net-Developer-Blog/Production-Certificate-...
However, we cannot submit transactions. Every transaction comes back with the mesage:
"An error occurred when attempting to connect with the credit card processor".
The SHA-2 patch was applied by Authorizenet overnight. Can someone help me troubleshoot this because Authorizenet support is not helping.
