Answer 1

Do you have a controller for home like you do for users? Looking at your call stack it appears you have one so I assume it's something like this if it isn't already.

class Home extends CI_Controller{
    public function index(){
        $data['results'] = $this->user_model->get_users();
        $this->load->view('main',$data);
   }
}

Then in your main.php passing the results data to the view_users view like so.

$this->load->view('view_users', $results);
