Hello how do I fix this issue?

I am new to this execution, on moving my site from local server to a live web server I am getting this error

Fatal error: require() [function.require]: 
Failed opening required   '__DIR__/views/home.php' 
(include_path='.:/usr/lib64/php:/usr/share/pear') 
in /home3/intvax0/public_html/answers/index.php 

Here is the code in my index.php.

<?php

ini_set('display_errors', 1);

define ('APP_ROOT', __DIR__);
define('BASE_URL', 'http://localhost/answers');
define ('VIEW_ROOT', APP_ROOT . '/views');

$dsn = 'mysql:host=localhost;dbname=mydbname';
$db = new PDO($dsn,'mydbname','mydbpass');

require 'functions.php';
