add_filter('post_type_link', 'my_post_type_link_filter_function', 1, 3);

I used this to add custom post type called story.
Permalinks : /%category%/%postname%/

I wanted the url to be: /parent-category/one-sub-category/post-title
Right Now it’s displaying: /story/parent-category/sub-category/
it’s not working.. the post-title is not included and it shows 404.

HELP ME PLEASE
