hello

j ai voulu upgrader mon site en utilisant le "pas a pas" conseillé... mais au final j ai cette erreur quand je vais sur mon site :

Warning: Cannot modify header information - headers already sent by (output started at /mnt/123/sdc/0/9/kopnord42/include/mysql.inc.php:10) in /mnt/123/sdc/0/9/kopnord42/include/common.inc.php on line 119


mon site : kopnord42.free.fr

voila le recapitulatif a la fin de l upgrade :
