I'm not sure how to solve this codeigniter error.

 

Error: Fatal error: Call to a member function library() on a non-object.

 

Controller

 

public function index()
{
	$this->load->helper('url');

	$this->load->library('header');

	$data['title'] 			= $this->header->get_page_name();
	$data['gutter_value'] 	= $this->header->get_gutter_value();
	$data['js_page'] 		= $this->header->get_js_page_file();
	$data['page'] 			= $this->header->page;
	$data['index_page'] 	        = $this->header->index_page;
	$data['nav_names'] 		= $this->header->nav_names;
	$data['banner_img']		= $this->header->get_banner_img();

	$this->load->view('includes/header', $data);

	$this->load->view('about/about_view');

	$this->load->view('includes/footer');
}

I got this problem long ago and  this helped me . It may help you too

public function index()
{
$ci=&get_instance()
	$ci->load->helper('url');

	$ci->load->library('header');

}
