SESSION paramaters not carrying over to other pages - php

Question

I have a login page which sets a _SESSION parameter of 'id' upon login. After logging in the user is redirected to the index.php page and at this point the session parameter is still set, I know this because I can print it with PHP. However, when navigating to the account.php page the parameter is lost and I am not sure why.
Most of the other questions asked on here regarding this are because of the session_start not being used but I have used this on the account.php page.
Any help in resolving this would be grateful.
The code for the account.php page is below:
<?php session_start(); ?>
<?php
$con=mysqli_connect("localhost","tkernick96","Tylerkernick1996","users");
if (mysqli_connect_errno())
{
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
$id = $_SESSSION['id'];
$query = mysqli_query($con,"SELECT * FROM users WHERE id = $id");
$row = mysqli_fetch_array($query,MYSQLI_ASSOC);
$firstname = $row ['firstname'];
$lastname = $row ['lastname'];
$email = $row ['email'];
$age = $row ['age'];
$nationality = $row ['nationality'];
$language1 = $row ['language1'];
$language2 = $row ['language2'];
$language3 = $row ['language3'];
$language4 = $row ['language4'];
$language5 = $row ['language5'];

Answer 1

it should be $_SESSION not $_SESSSION!
you should see a warning with the right error reporting level, e.g.
error_reporting(E_ALL);

Answer 2

Are you using IIS?
If it is, you should check the php.ini file (under c:\php or in c:\windows), find the session.save_path parameter, and be sure that points to a folder that exists.
Then edit the rights of that folder and give read/write permissions to the IUSR user.
If you're using Apache, you should find the user that is starting the daemon (you can find this in /etc/apache2/apache.conf), then be sure that that user have r/w permissions in the folder that php.ini session.save_path points.
Restart the IIS or Apache after that.
Hope it helps.
