Problem with payment gateway

[jackdebian]

I am trying to get the payment gateway 'fast charge' to handle my Zencart payments. In order to do this, we modified the authorize.net payment module (authorizenet.php) and changed the payment URL from this:

this->form_action_url = 'https://secure.authorize.net/gateway/transact.dll'

to this:

this->form_action_url = 'https://trans.secure-fastcharge.com/cgi-bin/authorize.cgi'

Now when I try a test purchase, I get to the order confirmation screen, and when I hit the 'confirm the order' button it contacts the payment gateway and then gives me the 'Whoops! Your session has expired' screen. The payment does go through, but the customer isn't notified of this in any way. The order isn't completed on the zencart side. Fastcharge is saying that it should work but it is not, anyone got any ideas?

try turning on force cookies

I turned 'Force cookie use' to true but still get the same thing 'Your session has expired' and the title says 'login time out'.

This may not help...
I'm getting the same error, using the Net1 payment module.
Have also tryed forcing cookie, but no change.

I posted a similiar question to the forum on Feb 11th , 07 with subject of
After Step 3 of 3, Shopping cart checkout produces "Whoops!...

After spending many MANY hours trying to configure for Fastcharge payments, I finally found this topic in the forum. I have the exact same problem. Wondering if you were able to solve the problem .. or if anyone else has any ideas I could try.

I would be happy to send all the details of my problem ......

Hi,

Did you ever solve the problem? If so, how?

I can find out the cause of it if you want?
