Custom Post Types and 404 Pages

Question

I have tried refreshing my permalinks but I still cant get this to work correctly.

I have the categories movies, gaming, blu-ray, and tv already created, so my URLs are site.com/movies/ for example. I would like for a post for movies to be at site.com/movies/post-here/ so for my custom post type my slug is `movies.

All my normal wordpress psots under the category movies are now 404ing while posts created specifically from the post type Movie Posts is working fine. Is this normal? Is there a step I'm not including?

Here are all my custom post types (Created with Custom Post Type UI):

//Movies Custom Post Type
register_post_type('movies_cp', array(  'label' => 'Movie Posts','description' => '','public' => true,'show_ui' => true,'show_in_menu' => true,'capability_type' => 'post','hierarchical' => false,'rewrite' => array('slug' => 'movies'),'query_var' => true,'exclude_from_search' => false,'supports' => array('title','editor','excerpt','trackbacks','custom-fields','comments','revisions','thumbnail','author','page-attributes',),'taxonomies' => array('category','post_tag',),'labels' => array (

Answer 1

If I understand what you are doing...

If you have categories set to load at "/category-name/" and a category named "/movies/" and a custom post type set to load at "/movies/" you've got conflicting elements. The rewrite rules are competing. That is going to be problematic. If you set has_archive to false when you register the post type, WordPress will not create the "/movies/" archive page and that might get you a step forward (though you won't have an archive page for the CPT), but you are still mixing category URLs and custom post type URLs so I'd expect there to be other problems.

My answer is going to be "I doubt you will ever get this working right and even if you can approximate something functional you probably shouldn't".
