403 forbidden (Créer un compte)

Bonjour,

Voici 2 jours que j’écume les forum et test les solutions sans succès.
Je possède le plugin Nextgen Gallery. Et plusieurs fonctions me sont inaccessible comme par exemple la page d’organisation des galleries et albums onglet « Album ».

Le problème viens du blocage des dossier nextgen sur mon FTP.

Tous les fichier et dossier de /www/wordpress/wp-content/plugins/nextgen-gallery m’indique en http, 403 (Forbidden).

Exemple :
http://alexandregirbal.com/wordpress/wp-content/plugins/nextgen-gallery/admin/images/nextgen_16_color.png
Le resultat est 403 forbidden

La console de google chrome m’indique :

GET http://alexandregirbal.com/wordpress/wp-content/plugins/nextgen-gallery/admin/css/menu.css?ver=3.5.2 403 (Forbidden)
GET http://alexandregirbal.com/wordpress/wp-content/plugins/nextgen-gallery/admin/css/jquery.ui.css?ver=1.8.5 403 (Forbidden)
GET http://alexandregirbal.com/wordpress/wp-content/plugins/nextgen-gallery/admin/css/nggadmin.css?ver=2.8.1 403 (Forbidden)
GET http://alexandregirbal.com/wordpress/wp-content/plugins/nextgen-gallery/admin/js/ngg_social_media.js?ver=3.5.2 403 (Forbidden)
GET http://alexandregirbal.com/wordpress/wp-content/plugins/nextgen-gallery/admin/js/ngg.autocomplete.js?ver=1.0.1 403 (Forbidden)
GET http://alexandregirbal.com/wordpress/wp-content/plugins/nextgen-gallery/admin/images/nextgen_16_color.png 403 (Forbidden)

J'ai bien autorisé les fichiers et le dossier en 777 sur mon server FTP.
desinstallé/reinstallé le plugin. Je pense que le problème peut venir des .htacces

.htaccess entrée de mon serveur:

SetEnv PHP_VER 5_TEST
SetEnv REGISTER_GLOBALS 0

.htaccess du dossier dossier WordPress :

# BEGIN WordPress
