Salve, oggi ho acquistato un dominio sul sito web4web
ho upplodato il mio progetto zend (non l'ho mai fatto prima) e quando vado a collegarmi alla mia pagina mi da il seguente errore

Warning: require_once(Zend/Application.php) [function.require-once]: failed to open stream: No such file or directory in /home/w50473/domains/bagnicarlomarotta.it/public/index.php on line 20

Fatal error: require_once() [function.require]: Failed opening required 'Zend/Application.php' (include_path=':.:/usr/local/php5.3/lib/php') in /home/w50473/domains/bagnicarlomarotta.it/public/index.php on line 20
Codice PHP:
<?php

// Define path to application directory
defined('APPLICATION_PATH')
    || define('APPLICATION_PATH', realpath(dirname(__FILE__) . '/../application'));

// Define application environment
defined('APPLICATION_ENV')
    || define('APPLICATION_ENV', (getenv('APPLICATION_ENV') ? getenv('APPLICATION_ENV') : 'development'));

// Ensure library/ is on include_path
$siteRootDir = dirname($_SERVER['DOCUMENT_ROOT']);

set_include_path(implode(PATH_SEPARATOR, array(
  realpath(APPLICATION_PATH . '/library'), // Here we have change
  get_include_path(),
)));
/** Zend_Application */
require_once 'Zend/Application.php';

// Create application, bootstrap, and run
$application = new Zend_Application(
    APPLICATION_ENV,
    APPLICATION_PATH . '/configs/application.ini'
);
$application->bootstrap()
            ->run();
ringrazio in anticipo tutti coloro che risponderanno. Cordiali saluti
