【问题描述】：

目前唯一的目标是顺利运行 Sitecore 页面编辑器。错误来自以下 URL：

http://localhost/sitecore/shell/Applications/WebEdit/WebEditRibbon.aspx?db=master&id={guid}&la=en&vs=1&url=%2F&mode=edit&sc_pagesite=website&trf=%2Ftemp%2Fdiagnostics%2Ftrace_{guid}.xml&prf=%2Ftemp%2Fdiagnostics%2Fprofile_{guid}.xml&dev={guid}

在启用页面编辑器的情况下打开任何页面时出现此异常：

16028 13:57:46 ERROR Application error.

禁用页面编辑器时页面呈现正常。

运行版本：

Sitecore 7.2。
ASP.NET MVC 5.2.3（也尝试过 5.1.3）。

我已尝试在布局/渲染中删除与 Sitecore 相关的任何内容，但该错误仍然存在。我意识到如果不查看配置文件就不可能弄清楚发生了什么，但希望有人曾经偶然发现过这个错误！

谢谢！

【问题讨论】：

是字面网址吗？其中没有任何实际的 GUID，这将是一个问题。另外，您正在编辑的网站是否在 web.config 中称为“网站”？
不，这不是文字 URL，我只是“隐藏”了 GUID。是的，它是一个叫做“网站”的网站，我已将 rootPath 属性更改为/sitecore/content/foo/bar。

标签： asp.net asp.net-mvc sitecore sitecore7.2

【解决方案1】：

问题在于 rootPath 属性。看来它不能低于/sitecore/content 的两个级别。当我将它从 /sitecore/content/foo/bar 更改为 /sitecore/content/foo 时，它再次起作用。希望 Sitecore 资深人士能够解释这是为什么！
