With pretty permalinks enabled, the URL of a Custom Post Format archive would look like this: http://example.com/type/link/ And it works for me. Now, considering that my custom post type archive is located at (where 'bookmarks' is the custom post type's name, registered with `'has_archive' => true`): http://example.com/bookmarks/ Isn't the custom post type's post format archive supposed to be located at: http://example.com/bookmarks/type/link/ But I get an HTTP 404 Not Found Error. Isn't it how it works? If not, how do I access the custom post type's post format archive?
