Custom Post Types Do Not work on this permalink setting https://somedominaname.com/%category%/%postname%/

The Permalink structure setting on the Permalink Settings admin page is only applied to the default post type, i.e. post. For custom post types (CPTs), you can set the permalink structure (for posts in your CPT) when registering your CPT, via the rewrite argument for register_post_type().

But, if you want to use %category%/%postname% with your CPT, then you should use a unique base like lingeries as in https://example.com/lingeries/category-slug/post-slug/, to avoid conflict with the default post type’s permalinks.

• So for example, if the category slug is foo-category and the post slug is foo-lingerie, then the permalink would be https://example.com/lingeries/foo-category/foo-lingerie/.

And here’s how can you achieve that:

1. Set your CPT’s rewrite slug to lingeries/%category%, i.e. 'rewrite' => array( 'slug' => 'lingeries/%category%' ).

2. Use the post_type_link hook to replace the %category% tag in the above structure with the correct post category slug.

3. Flush your rewrite rules (i.e. re-save your permalinks) by simply visiting the permalink settings page without having to click on the “Save Changes” button.

   And remember that you need to re-save the permalinks every time you changed the rewrite slug, including after you registered/added a new post type with rewriting enabled, e.g. when simply using 'rewrite' => true.

Sample code for replacing the %category% tag (in step 2 above):

add_filter( 'post_type_link', 'my_lingerie_post_type_link', 10, 2 );
function my_lingerie_post_type_link( $post_link, $post ) {
    // Do the replacement only if the post type is lingerie.
    if ( $post && 'lingerie' === $post->post_type ) {
        // Get the categories assigned to the post.
        $categories = get_the_category( $post->ID );

        // The category slug which will be used in the permalink, i.e. it replaces
        // the %category% tag.
        $category = '';

        // If there is a category assigned to the post, we use the first one.
        if ( ! empty( $categories[0] ) ) {
            $category_object = $categories[0];
            $category        = $category_object->slug;

            // If the category has one or more parents, let's add them to the
            // permalink. So for example, the permalink would look like
            // https://example.com/lingeries/parent-category/child-category/post-slug/
            // instead of https://example.com/lingeries/the-first-category/post-slug/.
            // (the-first-category refers to $categories[0])
            if ( $category_object->parent ) {
                $category = get_category_parents( $category_object->parent, false, "https://wordpress.stackexchange.com/", true ) . $category;
            }
        }

        // If there were no categories assigned to the post, then let's use a default
        // one. But it doesn't have to be "uncategorized", just use whatever you like..
        $category = $category ? $category : 'uncategorized';

        $post_link = str_replace( '%category%', $category, $post_link );
    }

    return $post_link;
}
