So with it in "Test" mode now, do I have to also have the eCart credentials in Test mode? I'm trying to use real credentials and I get as far as the checkout page and when I click continue I get "Transaction Not Completed. We're sorry. Your transaction could not be completed."
It never goes to the failure page. I get that message on the checkout page if that means anything.
I should mention I am trying this on my local server using MAMP Pro. And there is no SSL currently. Maybe this is the problem but I can't establish for sure what the problem is.
