En plus Free n'aime pas du tout les historiques et les statistiques...

Bonjour,

j'ai activé un plugin, et depuis, j'ai ce message quand j'accède à l'administration:

Warning: include_once() [function.include-once]: Unable to access ./plugins/GrumPluginClasses/classes/CommonPlugin.class.inc.php in /mnt/105/free.fr/7/4/goulan/photos/plugins/AStat/astat_root.class.inc.php on line 18

Que faire ?
Merci.
