检查文件/application/config/database.php并确保$query_builder = TRUE;我的猜测当前设置为FALSE。

我还建议将session加载为库而不是驱动程序。

$autoload['libraries'] = array('database', 'session');
//remove this line
//$autoload['drivers'] = array('session');

在会话配置中使用此

$config['sess_save_path'] = 'ci_sessions'; //assumes `ci_sessions` is the table name you are using

未为已配置的数据库启用查询生成器
