Hi there,
When trying to convert an online store from a classic theme to Twenty Twenty-Four, I encountered a problem. I could also reproduce it with a fresh WordPress installation using only the theme and WooCommerce:
Any set page template is not used for the checkout page, no matter which one you set in the editor. No navigation and no footer is displayed, only the page title.
After a lot of searching, I realized that the checkout page always uses the “checkout” template, even if another template is selected in the editor and is even rendered correctly after clicking on “Show Template”. Only when the corresponding template parts are inserted/replaced in the checkout template is the page displayed correctly in the frontend.
This is very confusing, which is also shown by other unresolved threads, e.g. https://wordpress.org/support/topic/crazy-header-2/ or https://wordpress.org/support/topic/checkout-page-issue-10/
Not sure if this is a WooCommerce or theme issue, but I think it’s worth adressing before more people get frustrated.
