eCart 5/confirm page fails to load payment page
I've uploaded my site and all works beautifully except when I click on the checkout button on the confirm page the payment page does not open and I get this error:
The following errors have occurred.
(99) This transaction cannot be accepted.
I'm not certain of what to do. Any suggestions?
I'm using authorize.Net as my gateway, and I've checked the credential info and it all seems to be okay.
