I know that it's impossible to have the same custom post type slug as a page.
So, I thought it might be resolved in this way:
'rewrite' => array('slug' => 'my-category/!#') for register_post_type
But I get "Page not found" every time I visit /my-category/!#/title-1
As you understand, I also have a page named "/my-category".
Is it somehow possible to resolve this conflict?
