I installed X-Payments and set it up yesterday, I was trying to use OPC with the new iFrame integration, but it had errors and I don't like how it turned out so we switched to FLC.
I noticed while using both FLC and OPC and submitting an order, the payment_cc.php file was corrupt or something. I am getting a 500 Error (internal error) when submitting an order:
"Server error
The website encountered an error while retrieving
https://MYDOMAIN.com/payment/payment_cc.php. It may be down for maintenance or configured incorrectly."
Any one else experience this or know how to fix this problem? This is currently a new web site I am trying to release and this is the only problem we have left before we release it. And since payment is a big part of the website, it has to wait..ha!
