问题描述

这是美好的一天，我走进工作和Sitecore的随机给了我这样的：

It was a beautiful day, and I came into work and Sitecore randomly gives me this:

[NullReferenceException: Object reference not set to an instance of an object.]
   Sitecore.UIUtil.GetBrowserClassString() +491
   Sitecore.sitecore.login.LoginPage.AddBrowserAttributes() +134
   Sitecore.sitecore.login.LoginPage.OnPreRender(EventArgs e) +434
   System.Web.UI.Control.PreRenderRecursiveInternal() +112
   System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +4296

这不仅是一个中断所说的天，这是完全无章可循。它不会出现，我或者我的团队所做的任何影响的变化，它一直工作正常。

Not only was this an interruption to said day, it was altogether out of nowhere. It does not appear that I or any on my team have made any affecting changes, and it's been working fine.

任何想法？

推荐答案

我们有这个问题，使用Sitecore的6.5多站点Sitecore的实例。问题是，作为@WeekendWarrior提到，在 Capabitilities 类型是空。我发现在解决方案;但是，我以为，因为你需要一个Sitecore的帐户来访问该论坛它会是有用这里复制发布答案的简单，快速修复部分：

We had this issue for a MultiSite Sitecore instance using Sitecore 6.5. The issue was that, as @WeekendWarrior alluded to, the Capabitilities Type was null. I found the solution on the Sitecore forum; however, I thought it'd be useful duplicate the simple, quick-fix part of the posted answer here because you need a Sitecore account to access the forum:

在您的默认网站的内容编辑器，找到 / Sitecore的/布局/设备/默认，并在该领域功能型 - ，组装输入：

In your default site Content Editor, locate /sitecore/layout/Devices/Default and in the field Capabilities Type - Type, Assembly enter:

Sitecore.Web.Configuration.InternetExplorerCapabilities，
Sitecore.Kernel

保存，然后发布项目。
