对于每个 PUT 或 DELETE 请求 WebDAV (sabre/dav)，我的 owncloud 安装都有内部服务器错误。请参阅我的 access.log 摘录：

同时我可以在 Apaches error.log 中找到这个：

根据 owncloud.log 看起来这是一个“拒绝访问”问题（至少对于取消链接消息），但是，相关的 Apache 用户具有完全权限，我使用 Sysinternals Process-Monitor 监控进度，它没有Access Denied 错误，只是 Success，但未找到。看截图：
http://bilder.ath.cx/temp/Process-Monitor.png
为了确保这不是权限问题，我还尝试将 Apache 作为本地管理员运行，这具有相同的效果。
我的设置是：带有 Owncloud 8.0.0.7、Apache 2.4.12 和 PHP 5.6.5 的 Windows 2k8 R2
我真的迷失了如何解决这个问题，有没有人提示我接下来可以尝试什么？
非常感谢您的帮助。
