Marketpress confirm checkout url stripe gateway

Marketpress 2.6.4 with stripe activated.

A user places an item is his cart and then goes through the checkout process. He enters his credit card number and then gets directed to the following url:

Stripe doesn't show a payment as being received.

Stripe mode is live and the secret key and publishable keys are entered.

The page says "checkout" and nothing else.
See image.

What step am I missing? Why is the confirm-checkout/ page pretty much blank?
