Erreur installation wordpress

Bonjour,


J'essaie desesperemment d'installer Wordpress.
Alors que tout semble ok, et qu'on me dit que l'installation c'est deroulé normalement, j'obtiens ce message:

"Warning: Cannot modify header information - headers already sent by (output started at /homez.520/cabinetbz/www/wp-config.php:1) in /homez.520/cabinetbz/www/wp-login.php on line 349
