I just updated PRO theme to newest version and I always used the pro theme for my checkout page.
I get an error now when checking out. The error says: {%%{childeren}%%}. Please see image below.

This is my pro checkout page in the backend. See image below. I use the shortcode [woocommerce_checkout] to generate the checkout on the page.
When I use a normal wordpress (NOT pro) page it does work. See image below.

See image below for the normal wordpress page backend.
How can I fix this problem? Since I always used my Theme X Pro page for my checkout page and I still want to use that page for my checkout page.
Looking forward seeing your reply.
Thanks.
