CodeIgniter_2.1.0 for a complete novice!

The constructors are now in PHP5-style.

Note the double underscore(__).

Code:

public class My_Controller extends Controller{
public function My_Controller ()
{
parent::controller();
}
}

is now

Code:

public class My_Controller extends CI_Controller{
public function __construct()
{
parent::__construct();
}
}

Same with the Models.
