Bonjour,
Effectivement ça ressemble à un problème avec le .htaccess qui est dans /zc_install/.
Dedans vous avez :
# $Id: .htaccess 3781 2006-06-16 04:33:28Z drbyte $
# The following disables mod_security in apache, which may be necessary during installation
# This file should only be used INSIDE the zc_install folder. Using the following directive elsewhere can
# cause security problems on your site. Talk to your webhost if you are concerned about its effects.
<IfModule mod_security.c>
SecFilterEngine Off
SecFilterScanPOST Off
</IfModule>
## If for some reason the above doesn't produce the desired results, simply remove the # from the
## following lines:
#SecFilterEngine off
#SecFilterScanPOST Off
Essayez de décommenter les deux dernières lignes pour avoir :
# $Id: .htaccess 3781 2006-06-16 04:33:28Z drbyte $
# The following disables mod_security in apache, which may be necessary during installation
# This file should only be used INSIDE the zc_install folder. Using the following directive elsewhere can
# cause security problems on your site. Talk to your webhost if you are concerned about its effects.
<IfModule mod_security.c>
SecFilterEngine Off
SecFilterScanPOST Off
</IfModule>
## If for some reason the above doesn't produce the desired results, simply remove the # from the
## following lines:
SecFilterEngine off
SecFilterScanPOST Off
Voyez si ça marche mieux. Si non, avez-vous accès au fichier d'erreurs (error.log en général) d'Apache pour le site concerné ? Cela permettrait d'avoir un peu plus de détails sur l'erreur.
