Dotnetnuke 升级DNN 9.0.1至9.2在PersonaBar失败

我们正在将DNN安装升级到9.4.4，以利用最新的内存泄漏修复程序。然而，我们遇到了麻烦，尽管尝试了几种升级路径，我还是没有取得任何进展

我最初是按照建议的升级路径升级到9.1.1，但在Newtonsoft.Json.dll上遇到了问题。我在某个论坛的帖子中看到，直接升级到9.2可能会更容易，因为Newtonsoft.Json在该版本的dnn中跨所有模块升级到了10.0.3版-我的扩展到了9.0.0，所以我想我只需要在整个站点上升级包

我仍然有Newtonsoft.Json错误，所以我按照所采取的步骤更新了我的web.config文件-我的程序集绑定重定向现在是

请确保检查newtonsoft.dll版本。第三方模块可能会将dll覆盖到更新版本，从而导致此问题

不久前我也有类似的问题，为我工作

另请检查上的故障排除指南

无论如何：您是否已经尝试过直接从9.0.1升级到9.4.4（确保服务器上安装了.Net Framework 4.7.2，否则会遇到问题）？建议的升级路径称为：建议
