I know this has been asked a million times but I am pulling out the little hair I have!
I have a custom post type called case-study (case-study.php and then linked in functions), a file called single-case-study.php and setup a post called test but I get a 404 when I go to website/case-study/test. I have tryed flush_rewrite_rules(); in my functions.php and after register_post_type('case-study' ,$args );, I have tried goingt to permalinks in the settings and saving and I have tried changing some of the things in the post register such as hierarchical or has_archive.
I have tried disabling all plugins, basically I have tried everything on this website How to Fix 404 and anything I could find on here. Does anyone know of anything else that could be casuing this?
Here is my register_post_type:
$args = array(
'label' => 'Case Study',
'public' => true,
'publicly_queryable' => true,
'show_ui' => true,
'query_var' => false,
'capability_type' => 'page',
'hierarchical' => true,
'has_archive' => false,
'rewrite' => array('slug' => 'case-study', 'with_front' => false),
'supports' => array('title', 'editor', 'thumbnail'),
'menu_position' => 31
);
register_post_type('case-study' ,$args );
