"session_start"

Bonjour,





Je suis entrain de créer un site, et j aimerai creer une sessiion
Mon site est pres, tout marche correctement sur mon serveur local ( j utilise wamp).

Qd je transfere mon site sur internet, j ai un gros soucis, le "session_start bug.

Voici mon message d'erreur:

"Warning: session_start() [function.session-start]: open(/mnt/168/sdb/6/0/nomdusite/sessions/sess_7ddb02a5b24b9223864b92a5386a3078, O_RDWR) failed: No such file or directory (2) in /mnt/168/sdb/6/0/nomdusite/tice/traitement.php on line 2

Voici mon code php de la page traitement.php:


<?php
// On démarre la session
session_start();



$_SESSION['nom'] = $_POST['nom'];
$_SESSION['prenom'] = $_POST['prenom'];
$_SESSION['promo'] = $_POST['promo'];

// Redirection du visiteur vers la page du minichat
header('Location: choix_planning.php');
?>




Ou est l'erreur?
Je suis sur free.fr..


Merci
