text_edit 未定义解决

 找到文件：admincontrollersetting    
 $data['heading_title'] = $this->language->get('heading_title');  
 后添加：
 $data['text_edit'] = $this->language->get('text_edit');

$data['heading_title'] = $this->language->get('heading_title');        $data['text_edit'] = $this->language->get('text_edit');
