I have just publish my ASP.Net MVC application online .. but all the actions and controllers work fine for registered users.
only one of them return 403 .. ?
locally everything works perfectly.
Any debugging suggestion will be very helpful.. any ideas as well
I know its something with the routing engine .. 
as the direct url : /UserPortal/Portal/Portal works well
 = Area,  = Controller,  = Action
But when i use: /UserPortal/
It returns 403 .. 
i have the following in my UserPortalAreaRegistration.cs
public override void RegisterArea(AreaRegistrationContext context) 
        {
            context.MapRoute(
                "UserPortal_default",
                "UserPortal",
                new { controller = "Portal", action = "Portal", id = UrlParameter.Optional }
            );
            context.MapRoute(
                "UserPortal_standard",
                "UserPortal/{controller}/{action}/{id}",
                new { action = "Index", id = UrlParameter.Optional }
            );
        }
