Legacy developer here on a project using X,
Project includes a child theme.
There is a custom header and footer on every page, hearder is using a navbar (class class="x-navbar-wrap" etc.)
After updating X, custom headers and footer are still there on home and every other pages made with Wordpress, but on custom pages generated by a custom plugin we don't have header and footer anymore.
Homepage (where it's still working) is using template_blank_4
Custom pages are generated via twig, calling at beginning a header function that just return get_header() and at the end a footer function returning get_footer().
Good news is we still get doctype, html tag etc. (after testing framework/views/header/base.php from last version of X is called) but no navbar anymore and no custom footer neither.
Any idea how to get that back please ?
Tell me if you need more information to help me.
Thank you for your time.
