DNN 7.0升级到7.4.1后报错（版本升级包）

Question

完成到 DNN 7.4 的升级后，出现如下错误。一切顺利，安装日志中没有错误。这发生在任何页面上，并且没有新的依赖关系 Visual Studio 我想...

知道我遗漏了什么或可能发生了什么吗？

Answer 1

所以这个问题最终是在 Ryan 正在升级的 DNN 网站的 BIN 文件夹中找到的自定义 DLL。

我解决这个问题的非科学方法是：

批量删除 BIN 文件夹中的 DLLS（保留一份 DLL 的副本，因为您不确定哪个是问题所在，测试后再放回去）
加载站点（使用 admin/site 设置页面）
查看页面是否仍然出错，如果是，重复步骤1和2

结束导致问题的 DLL 我相信 webservice/api URL 用于测试。删除它更正了他们正在使用的 DNN 7.3.4 实例上的问题。
