The c:\Users\fktho\.config\joplindev-desktop\log.txt
should actually contain new entries.
But I have seen one error, this is an error from the WebDAV server.

But an other problem is your sync target is empty?
Fail-safe: Sync was interrupted because 99% of the data (225 items) is about to be deleted. To override this behaviour disable the fail-safe in the sync settings.
