Ошибки при выводе в cignitere. что делать? триста раз уже всё проверил?

Это контроллер News.php

<?php

defined('BASEPATH') OR exit('No direc script access allowed');

class News extends CI_Controller
{

function public__construct()
{
parrent::__construct();
$this->load->model('News_model');
}

public function index() {
$data['title'] = "Все новости";
$data['news'] = $this->News_model->getNews();(cтрока 16)

$this->load->view('tamplets/header', $data);
$this->load->view('news/index', $data);
$this->load->view('tamplets/footer');
}

}

Это модель News_model

<?php

class News_model extends CI_Model
{

public function __construct()
{
$this->load->database();
}

public function getNews($slug = FALSE)
{
if($slug === FALSE)
{
$query = $this->db->get('news');
return $query->result_array();
}

$query = $this->db->get_where('news', array('slug' => $slug));
return $query->row_array();
}
}
