Hi,
when I activate my layout for portfolio posts, my header and footer are displayed as raw content on all affected pages which are set (portfolio post type).
I have activated layouts as suggested: How can I apply a custom layout to my portfolio pages?
Further I was told that the broken header could be a conflict with PHP 8. Trying to downgrading to PHP 7.4 hasn’t helped.
Looking forwards hearing from you, regards Jannes
