Pay Pal checkout failure
Paypal credentials are in place, the cart is live, but transaction fails for both express and credit card.
I suspect the problem might have something to do with the fact the we are only using the cart for class registrations that do not require shipping so my Global shipping settings are:
/* Shipping Settings */
$WAGLOBAL_Shipping_Enabled = false; //set to true if you intend to use shipping rate lookup.
