CodeIgniter不会在视图上显示更改

I'm working on a project using CI. But i'm having a problem. I have a view that isn't displaying its changes. I really don't know what its happening.

Lets say that I have application/views/store.php and the Store controller that loads that view. I update the php file but it doesn't change. Anyone has any idea of what it could be?

class Blog extends CI_Controller {

    public function index()
    {
           $data['title'] = "page title";

           $this->load->view('page',$data);
    }
}
