Something breaks while including a php class in ajax - php

Question

I am having a problem while including a php class with ajax.
Basically I have index.php which loads with ajax example.php. example.php includes init.php, which in turn includes a bunch of classes. I narrowed it down to users.php class, which I pasted below. I also put init.php under it just in case.
The file simply will not load with ajax. It works fine if i go directly to it.
<?php

init.php:
<?php
session_start();
require($_SERVER['DOCUMENT_ROOT'].'/core/connect/database.php');
require($_SERVER['DOCUMENT_ROOT'].'/core/classes/users.php');
require($_SERVER['DOCUMENT_ROOT'].'/core/classes/general.php');
require($_SERVER['DOCUMENT_ROOT'].'/core/classes/bcrypt.php');
require($_SERVER['DOCUMENT_ROOT'].'/core/classes/garage.php');
// error_reporting(0);
$users = new Users($db);
$general = new General();
$bcrypt = new Bcrypt(12);
$errors = array();
if ($general->logged_in() === true) {
$user_id = $_SESSION['id'];
$user = $users->userdata($user_id);
}
ob_start();
Here is the js loading the files (its a bit weird because its reloading jscrollpane, but working fine with html and php that dosent need external classes):
// Ajax
$(function () {
var api = $("#garagecontent").jScrollPane().data('jsp');
var reinitialiseScrollPane = function()
{
api.reinitialise();
}
// attaching click handler to links
$(document).on('click', '#garagecontainer a[href]', function (e) {
// cancel the default behaviour
e.preventDefault();
// get the address of the link
var href = $(this).attr('href');
// getting the desired element for working with it later
var $wrap = $('#garagecontent');
$wrap
// removing old data
api.getContentPane()
// load the remote page
.load(href, reinitialiseScrollPane , function (){
}
);
});
});
I have narrowed it down to users.php because it will work when I remove it from the includes (and its functions in init.php).
Can anyone spot what is breaking my code?

The solution to this question was using an autoloader. The page was breaking because of duplicate classes being called. My fault for having errors disabled i guess.
