Stripe.com payment integration module

[satello]

now i can manage to process the payment to the final stage, but then i get the usual

WARNING: An Error occurred, please refresh the page and try again.

payment is taken and emails sent, it's just the final checkout page now showing (done a live transaction of £1). how do I debug this? it happens as well with another stripe module from zucando, so must be down to my cart.

tried as well with cash on delivery method and the checkout show as it should/

any help would be much appreciated.

thank you, walter
