Bonjour

Je viens de développer une application ASP.net 4 avec un système de login via des formulaires et une base de données SQL, celle fournie par défaut dans VisualStudio 2010...

Mon application marche, en local... mais quand je la publie sur mon serveur... Le système de login ne marche plus et le serveur me renvoi l'erreur suivante:

Server Error in '/' Application.
