Ran the checkout wizard for about the 5th time (deleting all of the created files each time to ensure I have the newest files), and after an approval I get the same looping page that never loads. No orders/order details saved, just an infinitely loading page that has no content.
I ensured that when I selected PayPal Payments Advanced and nothing else on the second tab, so not sure what is going on.
This was supposed to make my job easier, but it has not. Please help!
