When finish the checkout, the Thank You page doesn’t show up the order detail (see attached).
First, I looked at the URL showing >> http://dorota.co/checkout/order-received/1817/
and found that the mission part is wc_order Key to be appended this url for displaying the order details.
Thank you so much for contacting our support center.
This page comes with WooCommerce plugin and its functionality doesn’t depend on our theme. Could you please check how it works with default WordPress theme to see if it is our theme issue or not?
