I have the same issue as @lwrkrol and here is my issue:
I created a Custom Post Type called “Careers” for a site, and in registering that, I put
‘show_in_menu’ => ‘edit.php’,
This puts the “All Careers” as a sub-item under Posts, which keeps my main menu cleaner and is desired.
However, when I go to /wp-admin/edit.php?post_type=career&page=re-orderPost-career I get “Sorry, you are not allowed to access this page.”
When I comment out the show_in_menu parameter, the same URL works great and says “Manually rank your “Careers”” and lets me rank them by a shared Custom Taxonomy called Cluster which holds Career Clusters (like Business, Science, Art, etc.) that is present for both regular Posts and the Custom Post Type Careers.
Is there a way to enable that URL if ‘show_in_menu’ puts it in a sub-menu like I’ve tried?
Thanks!
