Existe-t-il un équivalent à ce qui suit :
header("Content-type: text/xml");J'utilise Google Maps avec Wordpress et je reçois l'erreur "headers already sent". J'ai parcouru tous les fichiers et supprimé tous les espaces mais l'erreur apparaît toujours. Je me demandais donc s'il y avait une autre façon de faire le code ci-dessus.
Voici l'erreur :
Warning: Cannot modify header information - headers already sent by (output started at /home/medicom/public_html/mapping/wp-content/themes/default/header.php:11) in /home/medicom/public_html/mapping/wp-content/themes/default/new-version1.php on line 45Et voici ma page - http://www.mediwales.com/mapping/test/
