因为您不需要CPT archvie，最简单的使用方法example.com/new-site 打开页面，然后example.com/new-site/post-slug 要打开“新站点”帖子类型的单个帖子，需要声明has_archive => false 注册CPT时：

add_action( \'init\', \'cyb_register_cpt\' );
function cyb_register_cpt() {
    $args = array(
      // .....
      \'has_archive\' => false
    );
    register_post_type( \'new-site\', $args );
}

add_action( \'init\', \'cyb_register_cpt\' );
function cyb_register_cpt() {
    $args = array(
      // .....
      \'has_archive\' => false
    );
    register_post_type( \'new-site\', $args );
}

register_activation_hook( __FILE__, function () {
    cyb_register_cpt();
    flush_rewrite_rules();
} );

register_deactivation_hook( __FILE__, function () {
    flush_rewrite_rules();
} );
