We just upgraded to 3.9.3 on our production site and our dev site, both of which are on the same (apache/linux) server. Since upgrading webdav has stopped working properly.

Most webdav functionality is still there, you can log on, browse folders, move objects and rename objects. But when you try to drop an image or a PDF into one of the online folders you get an error message (in Windows - "an error ocurred copying all or some of the selected files" , in Webdrive an 'error #5') and the operation fails.

The server error logs are not showing anything special.

We have another site on the same apache web server, but running 3.9.1, which is still running webdav perfectly.

Another user is also reporting problems with 3.9.3 in the forums

I have posted a request for reports of webdav working or not working in 3.9.3 in the forums, but so far have had no response.

Steps to reproduce

drag and drop files into webfolders in 3.9.3
