母版页布局不可见

Question

我使用 Visual Studio 2010 Ultimate 创建了一个网站，当我开始创建它时，它在调试和在浏览器中查看时显示正确。但是，现在由于某种原因，它没有显示正确的布局。它只显示文本和控件。它不显示包含内容格式的颜色或其他布局内容。有没有其他人遇到过这个问题？作为记录，我从未修改过 Site.master 页面。我也清除了缓存并重新启动了 Visual Studio。该网站在“设计视图”中正确显示，但在 Web 浏览器中显示不正确。关于如何解决此问题的任何想法？这是我无法启动的“Login.aspx”页面的代码。

<%@ Page Title="Dodge Main" Language="VB" MasterPageFile="~/Site.Master" AutoEventWireup="false"
CodeFile="Login.aspx.vb" Inherits="Account_Login" %>

事实证明这是一个安全问题。当我从设置中删除所有角色和安全性时，外观恢复正常。很奇怪。
