Hi @James
I tried the default theme, but the result is the same. And this only happens on a particular post type. I have 3-4 more post types and editing one of them works correctly. I am using the theme’s functions file to add the acf_form_head() tag on all relevant pages.
I would assume that even without the acf_form)head() tag, the form would at least show up, but this does not happen. The page does not even change, although the URL does and that’s when I get the error.
