There is no CodeIgniter __construct in the Controller anymore.
Leave the parent::__construct() out.
If you look at system Controller.php you will see that there is no constructor method
It's added to the BaseController for passing parameters to the other controllers.
Also remove the helpers ad the begging of the BaseController it is in the Controller now.
