Problems with altervista

This is my code:

Code:

<?php
defined('BASEPATH') OR exit('No direct script access allowed');

class Welcome extends CI_Controller {

function index()
   {
       $this->load->model('home_model');

       $data['n'] = $this->home_model->Novita();
       $data['v'] = $this->home_model->Venduti();
       $this->load->view('primaview');
       $this->load->view('menu');
       $this->load->view('home', $data);
       $this->load->view('footer');
   }
}
?>

Also the folder "membri" that appears in the path is not part of my site but I think it's part of altervista

Code:

Message: Unable to locate the model you have specified: Home_model

Filename: /membri/****/system/core/Loader.php
