X3Photo Gallery Forums

I have a small problem display cases. The menu of the gallery displays "indefined" while I have the file exists on the server?
example:
galerie/content/galerie1
galerie/content/galerie1/dossier1
galerie/content/galerie1/dossier2
galerie/content/galerie1/dossier3

galerie/content/galerie2
galerie/content/galerie2/dossier1
galerie/content/galerie2/dossier2
galerie/content/galerie2/dossier3

Know why? it must configure something special in the admin?
my file content is well CHMOD 777 and any sub folder content
and the folder as admin

I think there's a bug, because now everything is working well.
can be a history cache

Thanks !
