Question

After finishing the web application and publishing it online no matter I try I keep getting the following error, keep in mind that it runs locally as it should...

    {
        protected void Page_Load(object sender, EventArgs e)
        {
            string admin = (string)Session["Admin"];
            if (string.IsNullOrEmpty(admin))
            {
                logout.Visible = false;
            }
            else
