I have a custom theme, all (custom) content types display as expected except basic pages. Is there something fundamentally different to basic pages that explains/ helps me to troubleshoot why the markup is different?
The site has custom theme/child-theme, custom modules, and a heap of contrib modules so I can't really "paste the code", and as it's a development site I can't give access to it.
The problem I'm experiencing seems to be HTML markup errors, some missing closing elements etc., but I've stepped through most of the code already and can't see anything. Is it something specific to basic pages that Drupal does differently?
