Bonjour,
J'ai procédé à une mise à jour automatique de ma galerie de Piwigo 2.0.1 vers 2.1.2.
J'ai réalisé les sauvegardes comme indiqué et lancé la MAJ.
Résultat: ma galerie n'est plus accessible avec le message suivant:
"Statut de l'utilisateur "guest" non conforme, utilisation du statut par défaut. Veuillez prévenir le webmestre."
Suivi du texte suivant:
