Re: CyberSource Internal Error
Turns out that the issue was that I was using the URL path to the key file and not the server path. It's unfortunate that I had to spend $140 with X-cart and hours and hours of development time -- not to mention that I missed my deadline -- for something that should have been outlined clearer in the installation instructions. I'm happy it was an easy fix, but it should have been avoided altogether...
X-Cart version 4.5.4
