New Post: Custom payment gateway

Hi Fahad,

I'm having a similar problem with a custom payment gateway. It's working on one site, but in a new one it's giving me an error when i try to go to the payment phase, and redirects me to the link /CheckOut/tabid/93/ctl/RemotePost/mid/421/Default.aspx.
Have you ever solved this issue?

Regards,

David
