我刚刚将我的WP站点从一台服务器移动到另一台服务器，我的自定义帖子类型插件导致以下错误：

Warning: call\\u user\\u func\\u array（）要求参数1是有效的回调，在/var/sites/*/****中找不到函数“my\\u admin”，或函数名无效。com/public\\u html/wp-includes/plugin。php在线496

我的自定义帖子类型代码如下：

function all_post_types() {
    create_video_camera();
    create_stills_camera();
    create_lens();
    create_light();
    create_sound();
    create_aerial();
}

add_action( \'init\', \'all_post_types\' );

function create_video_camera() {

    $labels = array(
        \'name\'                => _x( \'Video Cameras\', \'Post Type General Name\', \'******\' ),
        \'singular_name\'       => _x( \'Video Camera\', \'Post Type Singular Name\', \'******\' ),
        \'menu_name\'           => __( \'Video Camera\', \'******\' ),
        \'name_admin_bar\'      => __( \'Video Camera\', \'******\' ),
        \'parent_item_colon\'   => __( \'Parent Video Camera:\', \'******\' ),
        \'all_items\'           => __( \'All Video Cameras\', \'******\' ),
        \'add_new_item\'        => __( \'Add New Video Camera\', \'******\' ),
        \'add_new\'             => __( \'Add New\', \'******\' ),
        \'new_item\'            => __( \'New Video Camera\', \'******\' ),
        \'edit_item\'           => __( \'Edit Video Camera\', \'******\' ),
        \'update_item\'         => __( \'Update Video Camera\', \'******\' ),
        \'view_item\'           => __( \'View Video Camera\', \'******\' ),
        \'search_items\'        => __( \'Search Video Camera\', \'******\' ),
        \'not_found\'           => __( \'Not found\', \'******\' ),
        \'not_found_in_trash\'  => __( \'Not found in Trash\', \'******\' ),
    );
    $args = array(
        \'label\'               => __( \'video_camera\', \'******\' ),
        \'description\'         => __( \'Video Camera Template\', \'******\' ),
        \'labels\'              => $labels,
        \'supports\'            => array( \'title\', \'editor\', \'thumbnail\', ),
        \'taxonomies\'          => array( \'category\', \'post_tag\' ),
        \'hierarchical\'        => false,
        \'public\'              => true,
        \'show_ui\'             => true,
        \'show_in_menu\'        => true,
        \'menu_position\'       => 25,
        \'menu_icon\'           => \'dashicons-video-alt\',
        \'show_in_admin_bar\'   => true,
        \'show_in_nav_menus\'   => true,
        \'can_export\'          => true,
        \'has_archive\'         => true,      
        \'exclude_from_search\' => false,
        \'publicly_queryable\'  => true,
        \'capability_type\'     => \'post\',
    );
    register_post_type( \'video_camera\', $args );

}

这一切都在旧服务器上运行得很好，但现在我发现了错误。我尝试过其他解决方案，但没有成功。

提前感谢：）
