Blank page when website is hosted online

Question

I have build a small website with some php. It works perfectly on my localhost (even without database information it loads the html and css).

However when I put it online I just get a blankpage, no errors, nothing. However when I manually type a page it redirects to the login page (which is good).

Anyone experienced this before?

Thanks EDIT2: After some debugging advice I got this error

Warning: include_once(classes/users.class.php): failed to open stream: No such file or directory in /customers/c/2/9/nicolasdecroos.be/httpd.www/eindwerk/login.php on line 8 Warning: include_once(): Failed opening 'classes/users.class.php' for inclusion (include_path='.:/usr/share/php') in /customers/c/2/9/nicolasdecroos.be/httpd.www/eindwerk/login.php on line 8 Fatal error: Class 'user' not found in /customers/c/2/9/nicolasdecroos.be/httpd.www/eindwerk/login.php on line 9

Edit: Here is the PHP code on the login page

<?php
session_start();
    include_once("classes/users.class.php");
    $user = new user();

    if(isset($_SESSION['loggedin']))
    {
        header('location: index.php');
    }
    else
    {
        if(!empty($_POST))
        {
            try
            {
                $user->login($_POST['studentennummer'],$_POST['password']);
            }
            catch (Exception $error)
            {
                $message = $error->getMessage();
            }
        }
    }
?>

This is users.class

*Sorry if it's to much code, I'm not sure which part would be the most interesting.

<?php
    include_once("classes/db.class.php");

    class user

                case 'Studentennummer':
                    return $this->m_sStudentennummer;

Alright,

It was something dumb but I'll post it incase someone has troubles with this.

The map was called "Classes". in the code it was written as "classes".

On localhost it wasn't a problem, but when you put it online it is.
