- On 'website_payment/pay' if the reference contains a '/' the payment will never succeed.
It is due to the fact that in the template "payment.pay" were setting "prepare_tx_url" and "form_action" using this reference.
But having a '/' in the reference breaks the URL to call to create a transaction.
So when creating a transaction (or even paying in S2S) the payment never succeed and returns a HTTP 404 error.
