WordPress - 致命错误：在第106行的C：\ inetpub \ wwwroot \ wp-includes \ class-wp-widget-factory.php中找不到类'WP_Widget_Tag_Cloud'

Question

突然收到此错误

Fatal error: Class 'WP_Widget_Tag_Cloud' not found in class-wp-widget-factory.php on line 106

根本没有变化。停用所有插件并更改主题，仍然是此错误

public function register( $widget ) {
        if ( $widget instanceof WP_Widget ) {
            $this->widgets[ $this->hash_object( $widget ) ] = $widget;
        } else {
            $this->widgets[ $widget ] = new $widget(); // LINE 106
        }
    }

有什么想法吗？

现在也来了

Fatal error: Class 'Vc_Role_Access_Controller' not found in wp-content\plugins\js_composer\include\classes\core\access\class-vc-current-user-access-controller.php on line 7
