c# - 发布后出现奇怪的禁止访问错误

Question

我得到：

在我将我的网站发布到 IIS 服务器之后，在我使用正确的凭据按下登录按钮之后。它在我的本地机器上运行良好，应该将我转移到ControlPanel.aspx页面。

登录按钮代码：

    protected void BtnSubmitClick(object sender, EventArgs e)
    {
        using (var db = new DbContext())
        {
            if (db.Users.Any(x => x.Username == txtUserName.Text && x.Password == txtPassword.Text))
            {
                FormsAuthentication.RedirectFromLoginPage(txtUserName.Text, true);
            }
            else
            {
                ClientScript.RegisterStartupScript(GetType(), "myalert", "alert('* invalid credentials, please try again');", true);
            }
        }
    }

我认为这可能与 web.config 有关：
