Unable to locate the specified class: Session.php

This weekend I migrated to version 3.1 coming from 2.2.6.

Unable to locate the specified class: Session.php

I googled and a lot of hits but not the right one for me.

In autoload.php I have:

PHP Code:

$autoload['libraries'] = array('database', 'user_agent');
$autoload['drivers'] = array('session'); 


But I am wondering what is the best way to use sessions in my controller.


Is thrown in my first sub class derived as follows.

PHP Code:

class MY_Ezbuild extends CI_Controller {

  function __construct() {
    ob_start();
    parent::__construct();
    $this->outputdir = "/htdocs/b4y_v18/";
    $this->load->library('session'); 


Here fore I need session data in my construct of MY_Ezbuild:

PHP Code:

    $this->session->set_userdata('language', 'NL');
    $this->session->set_userdata('poolID', '1');
    $this->session->set_userdata('labelID', '1'); 


Any help more than appreaceated.
