dotnetnuke - 升级到 DNN 9.2.2 时搜索结果模块“发生严重错误”

问题描述

从 DNN 7 -> DNN 9.2.2 升级后，我的搜索结果模块出现问题

每次我使用 DNN 的 Xcilion（内置搜索）进行搜索时，我都会不断收到“发生严重错误。请查看事件查看器以获取更多详细信息。” (/Default.aspx?tabid=87&error=Object+reference+not+set+to+an+instance+of+an+object.&content=0) 搜索结果页面出错。

我试图通过删除搜索文件夹中的内容来重新索引，即https://dnnsupport.dnnsoftware.com/hc/en-us/articles/360004881174-Search-Not-Showing-Expected-Results

已从 /desktopmodules/admin/searchresults 备份旧文件并添加新文件，以防安装过程中出现问题，与可能影响搜索的 DLL 文件相同。

任何提示或想法都会很棒，其他一切都在这个 DNN 实例上正常工作，只是无法解决这个错误。
