Cannot modify header information - headers already sent

Version imprimable

Bonjour,

Je sais que beaucoup de messages sont postés sur le sujet (j'en ai déjà lus pas mal, sans pour autant réussir à solutionner mon problème).

Quand un nouveau client s'inscrit sur mon site, la validation du formulaire enregistre correctement toutes les données dans la base par contre, au lieu d'ouvrir la page vers laquelle il devrait être redirigé, le client se retrouve devant le formulaire d'inscription (vide) qu'il vient de remplir et il y a l'erreur suivante qui s'affiche :
Warning: Cannot modify header information - headers already sent by (output started at /wxxx/inscription.php:5) in /xxx/inscription.php on line 83

Voici la ligne 83 :

Code:

header(sprintf("Location: %s", $insertGoTo));

J'utilise cette ligne de code dans d'autres fichiers (ex : ajout fiche produit) et ça fonctionne. Je n'arrive pas à voir la différence... :oops:

Voici tout ce qui se trouve avant mon doctype :

J'espère que quelqu'un pourra m'expliquer comment pallier cette erreur.

Bonsoir,

Peut-être qu'en ne faisant qu'un seul bloc PHP ?
