SharePoint-多文档上载-不允许HTTP“Post”谓词

当尝试上载任何数量的文档(包括非常小的文件)时,似乎成功了-但随后重定向到一个错误页,指示以下内容:

/_layouts/error.aspx?ErrorText=The%20HTTP%20verb%20POST%20used%20to%20access%20path%20%27%2F%5Fvti%5Fbin%2Fshtml%2Edll%2FSiteCollectionDocuments%2FForms%2FUpload%2Easpx%27%20is%20not%20allowed%2E

不允许使用用于访问路径“/u vti_bin/shtml.dll/sitecollectiondocuments/forms/upload.aspx”的HTTP谓词日志。

有什么关于为什么这个操作会拒绝HTTP Post的想法吗?

更新:

直接导航到/_vti_bin/shtml.dll/sitecollectiondocuments/forms/upload.aspx提供:

无法显示XML页 无法使用样式表查看XML输入。请更正错误,然后单击“刷新”按钮,或稍后再试。

在文本内容中发现无效字符。处理资源时出错' http://sitename/ … MZ

事件日志中的错误如下:
