變化'$分貝[ '缺省'] =陣列（ 'pconnect'=> FALSE ）;'在database.php中和焯芬 – Saty

或者'config ['sess_save_path'] ='ci_sessions''在config.php文件中 – Saty

檢查文件/application/config/database.php，確保$query_builder = TRUE;我猜它的當前設置爲FALSE。

我也建議將session作爲庫加載而不是驅動程序。

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

在會話配置使用本

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