session codeigniter localhost

I'm using this Facebook lib for CodeIgniter so users can login with Facebook. Works perfectly fine on production, but not on localhost. The thing that is bugging me is that it used to work fine on localhost, but suddenly stopped working.

I've been searching for some time and I'm expecting that this has something to do with CI's session library, but I'm not 100% sure.

Background info

The problem

What I already tried and did not work

Additional info on config.php

$config['cookie_prefix']    = "";
$config['cookie_domain']    = "";
$config['cookie_path']      = "/";
$config['cookie_secure']    = FALSE;

I hoped that using PHP's native session would resolve the problem, but it didn't. Not sure what else I can try.

For reference the full Facebook.php library file code

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

if ( session_status() == PHP_SESSION_NONE ) {
    session_start();
}

require_once( APPPATH . 'libraries/facebook/Facebook/GraphObject.php' );
require_once( APPPATH . 'libraries/facebook/Facebook/GraphSessionInfo.php' );

The library you are using is external to the core CodeIgniter codebase and therefore isn't able to communicate with native functions in the normal way; instead of using $this as your reference to the CodeIgniter instance, in your library you should be using $this->ci so to access session data, your code would look something like:

$this->ci->session->userdata();

This is explained in more detail in the CodeIgniter documentation here

in the view use $this->facebook->session instead of $this->session and it will work ;)
