I recently tried to update my Gold Cart plugin and noticed that Authorize.net, along with other Payment Gateways have disappeared from the Settings>Payment screen.
The issue is that I'm running Gold Cart 2.8 and using Authorize.net. The upgrade to 188.8.131.52 seems to remove this gateway/feature.
Is this intentional or is it a bug caused by upgrading?
I also noticed that you have a new premium add-on for Authorize.net. Did you strip these features from the free version/gold cart upgrade in order to sell them individually?
