Custom page template not being called

Question

I've been learning Wordpress for the last few days but I'm having an issue with custom post types.

I've registered the post type as below:

function create_kitchen_type() {
    $kitchen_args = array(
            'labels' => array(
                'name' => __( 'Kitchens' ),
                'singular_name' => __( 'Kitchens' )
            ),
            'public'      => true,
            'has_archive' => true,
            'description' => 'Kitchen custom post type description',
            'supports'    => array(
                'title',
                'editor',
                'comments'
            ),
            'taxonomies'  => array('category'),
            'rewrite'     => array(
                'pages' => false
            )
    );
    register_post_type( 'kitchen_post', $kitchen_args );
};
add_action( 'init', 'create_kitchen_type' );

In index.php the post types (currently just one) are outputted like so:

$custom_post_args = array(
        '_builtin' => false,
        'public'   => true
);

$post_types = get_post_types( $custom_post_args, 'objects' ); 

foreach ( $post_types as $post_type ) {
    echo '<a href="' . $post_type->name . '">' . $post_type->labels->singular_name . '</a>';
};

// Outputs: <a href="kitchen_post">Kitchens</a>

Then, when the link is clicked, the address bar displays localhost/site_name/kitchen_post but the title is "Page not found | ", and the single echo that I've added to archive-kitchen_post.php is not displayed.

So, why isn't archive-kitchen_post.php used?

Thanks in advance.

Ok, so it turns out this was simply a case of going to Settings > Permalinks and merely saving. This reset the permalink structures.
