Question

我在Windows Server 2008（而不是R2）上安装了dnn。

我的DNN安装似乎一切正常，但当我进入我的商店凭据时收到以下错误

Critical Error: Object reference not set to an instance of an object.

进入管理员＆gt;事件查看器我看到一些带有以下内容的条目

安装论坛模块时遇到了类似的问题。我无法得到如何解决它的答案。我最终安装了它的旧版本，它工作正常。此外，请确保该站点的文件和文件夹的所有权限都设置为读取和写入..我有一些文件和文件夹的问题，没有设置为读写，并继续抛出错误消息...如果你真的被卡住了我建议使用下面列出的论坛。 http://www.dnnsoftware.com/forums
