2SXC-SearchIndexException：搜索：索引模块出错

Question

我遇到了可怕的DNN错误“发生了意外错误”，并带有返回站点的链接。这里没有显示其他信息，因此我检查了\Portals\_default\Logs\下的日志并找到了：

[不幸的是，自从8月初进行演示以来，我还没有接触过该站点，在那里创建了示例帖子，这意味着我不知道该怎么做导致错误。那时我没有收到任何错误消息，并且在获得大假发的批准后，我将精力转移到了其他项目上，并且不记得做任何平常的事情或遇到任何错误。但是我今天尝试访问该网站，但遇到与2SXC相关的这些错误。

这些错误是什么意思，我该如何解决该问题以恢复我的网站？

更新：我正在使用新闻应用程序03.01.04运行DNN 9.1.1和2SXC 09.32.01

更新2：我也注意到此错误：

Answer 1

我的问题实际上与2SXC无关。在关于原始问题的更新2中，我提到我还注意到一个错误，说：

System.Web.HttpParseException: The file '/DesktopModules/DDRMenu/Menu.ascx' does not exist.

这显然是Visual Studio中DNN模块开发的常见问题。从 HemIT Blog：

此虚拟目录来自何处？在我的开发环境中，它来自以下事实：

• 我们正在使用SVN，我倾向于检出模块并在IIS网站之外进行编译
• 我正在使用著名的christoc模板进行模块开发（请不要误解我，这太好了！这只是在做我们可能无法预见的事情，我们只是在做背后的事情。）确实，如果我查看项目文件：

真正的罪魁祸首是Visual Studio！

当您检出模块时，如果您在IIS上配置了站点，则项目将正常打开。但是，在编译时，如果您不在IIS网站上，则会创建一个虚拟目录“ desktopmodule”，并隐藏“ DesktopModules”文件夹。

因此，DNN无法再找到DDRMenu模块，因此它失败了。

解决方案非常简单。进入IIS并删除标记为“ desktopmodules”的虚拟目录：
