Transaction failing when testing new site
I am rebuilding a site using eCart 6 and MySQLi. I have uploaded all of the files to a folder within the current site root so that I can do some live testing before we actually launch. Everything looks to be operating correctly until I attempt to checkout. Both PayPal and Authorize.net payments fail. I have looked through the code and can't seem to figure out why. This is the result I get on the checkout_failure page when I attempt to get the Authnet_Result: Fatal error: Call to undefined function AuthNet_Result(). I did double-check that all of the files have been uploaded (including the AuthNet_PHP.php where the function exists).
Can this have something to do with trying to communicate with the payment processors from within a folder? The current site operates fine and it was built with an earlier version of eCart.
