Salut,

J'étais en train de transférer mes photos sur mon site quand je me suis rendu compte que quand on arrivait sur le site sans être connecté, on avait droit à cette erreur:

SELECT cat_id
  FROM phpwebgallery_user_access
  WHERE user_id =

Pouvez-vous m'aider pour corriger cette erreur?

Merci beaucoup d'avance,
