Since I activate the encryption I get an error with shared files.
This is an file that Uploaded over webdav from am worktime App for Android.

Couldn't re-calculate unencrypted size for files_versions/TimeRecordingPro/backup/timerec.db.gz.v1467660003

this is the Android App: Zeiterfassung Pro
Zeiterfassung Owncloud upload plugin

Did you follow the hint and reshare the file/folder? If you haven’t enabled encryption during installation, the shared encryption-keys have to be issued.

I forgot this step. Thanks.

I have this encryption problem for one file. But its an Temp file. After Upload finished the file doesn´t exists.

Couldn't re-calculate unencrypted size for files_versions/TimeRecordingPro/backup/timerec.db.gz.v1467660003

After upload only /TimeRecordingPro/backup/timerec.db.gz exists…
Any idea?

This is a file from versioning (old version of timerec.db.gz. You can open a new topic for that. If that is perhaps a side effect from starting the encryption, you can just wait to the old version to be removed (will be automatically done after a grace period) and only report it, if this error comes back again.
