I'm pulling my hairs out for this one. I want to customize my order submitted/what's
next page by adding an image and a payment link for banktransfers with iDEAL/Bancontact/SOFORT/etc.
I thought I simply needed to update the message template 'Edit Order Submitted
Page'. But the text I enter here does not show up when I place an order.
Where do I customize this page?
