在 DNN 上从 Evoq Content 降级时安装 2sxc

Question

正如标题所示，我们有一个 DNN Evoq 内容网站，已降级为平台。我们想要在 2sxc 应用程序中重建 Evoq Content Visualizer。安装 2sxc 不是问题。当我将应用程序模块放到页面上时，我看到“view.ascx 中出现了严重错误 - 检查错误日志”。

查看日志，我看到下面这两个错误。同样奇怪的是我的系统上没有 C:\Projects 文件夹。

Answer 1

首先，显示“

C:\Projects\...

”的消息只是为了表明哪一行代码出了问题。这是编译 2sxc 的地方，你不会有那个文件夹。

请注意，各个公司都在 Evoq 中运行 2sxc，因此它确实有效。我不确定你的系统出了什么问题...

它说找不到连接字符串。 我的猜测是要么

1. 您做了一些特殊的事情，因此连接字符串不在

   web.config

中的正常位置
2. 启动时有些东西没有正常运行，导致连接字符串没有被尽早拾取。

最好深入挖掘一下。另请查看 2sxc-insights，因为它们从一开始就包含日志 - 因此加载时失败的任何内容都应该显示在那里。
