New Post: Using Plugin on nop 2.65

All I did was add the button after the shipping selection:

<divclass="checkout-paypal-express">
                        @Html.Action("PaymentInfo", "PaymentPayPalExpress", new { routeName = "Plugin.Payments.PayPalExpress.PaymentInfo" })
                        - or-
                    </div>

And it works great in the sandbox mode, but when I take it to production, at the last step it just redirects back the Nop site's
home screen with no money taken or order placed... Is there something special besides enabling API access on Paypal to get this to work
or am I missing something?
