You should post the actual error.
Anyway, the problem is caused here.
Code:
public $data['header'] = $this->load->view('header', null, TRUE);
Change To:
Code:
public $data['header'] = '';
public function __construct() {
parent::__construct();
$this->data['header'] = $this->load->view('header', null, TRUE);
