Have you tried uploading the file with an ownCloud client, that doesn’t have VFS enabled and therefore ruled out a server issue?

Hi Eneubauer,

Thanks for your reply! Yes — as soon as I disable virtual files, the problem completely disappears. It seems to be an issue with that feature.

Michael

the problem persist, I have 2.8.2 version of the client, and as long as I don’t close Microsoft Excel, the error metadata’s showed. The solution isn’t pass to disabled VFS, because I need of VFS.
When would this problem be resolve?
thanks

Could you check with the 2.9 daily builds?

Hi, when you see this problem, is there any “Endpoint Protection Software” such as Antivirus running on the windows client machine?
