Class 'CI_Driver_Library' not found codeigniter error

Question

I want to use session, so I try to do autoload. In application > config.php, I do $autoload['libraries'] = array('session');

but I got below error

Message: Class 'CI_Driver_Library' not found

Filename: Session/Session.php

Answer 1

If your using Codeigniter 3.0 or higher use this:

$autoload['drivers'] = array('session');

Because the session is a driver not a library after version 3.0!

Under Version 2.1 it's a library!
