WP custom page type but problem page not found

I create a custom post type to see this article link given.

https://www.wpbeginner.com/wp-tutorials/how-to-create-custom-post-types-in-wordpress/

use this code:

// Our custom post type function

function create_posttype() {

    register_post_type( 'movies',

    // CPT Options

        array(

            'labels' => array(

                'name' => __( 'Movies' ),

                'singular_name' => __( 'Movie' )

            ),

            'public' => true,

            'has_archive' => true,

            'rewrite' => array('slug' => 'movies'),

        )

    );

}

// Hooking up our function to theme setup

add_action( 'init', 'create_posttype' );










but the problem is when i add a article and click the peralink it show page not found.







solve this to go setting->permalink then check Post Name.
