Dans index.php vous devez mettre cette condition if en haut après 'session_start();'
if($_SESSION['username'])
{
header("Location: home.php");
exit();
}
Dans la boucle while, cela devrait être header("Location: home.php"); au lieu de header("Location: index.php");
Dans home.php page que vous devez mettre en haut après l'ouverture de la balise php
ob_start();
session_start();
J'espère que ça marchera.

Utilisez ce codeindex.php
<?php
require_once('connect.php');
ob_start();
session_start();
//checked wether the user is loged in or not
$user = $_SESSION['username'];
if($_SESSION['username'])
{
$user = $_SESSION['username'];
header("Location: home.php");
exit();
}
// login script
if(isset($_POST['username'])&& isset($_POST['password']))
{
$user_login = preg_replace('#[^A-Za-z0-9]#i', '', $_POST['username']);
$user_password = preg_replace('#[^A-Za-z0-9]#i', '', $_POST['password']);
$md5password = md5($user_password);
$sql = mysql_query("SELECT id FROM members WHERE username = '".$user_login."' AND password = '".$user_password."'") or die ("could not select from database");
$userCount = mysql_num_rows($sql);
if($userCount ==1)
{
while($row = mysql_fetch_array($sql))
{
$id = $row['id'];
}
$_SESSION['id'] = $id;
$_SESSION['username'] = $user_login;
$_SESSION['password'] = $user_password;
header("Location: home.php");
exit();
}
else
{
echo "that info is incorrect";
exit();
}
}
?>
