Hey hodyroff,
I do know that this feature should be working but it doesn’t - that’s why I am looking for help/hints in the first place. 
I’m using local storage and there is enough quota/free space. Even if there wasn’t enough quota it should be possible to get access to this directory since the owner could create it and has access to it. (so it should be - at least - downloadable)
Repairing with occ etc didn’t work for me either. My assumption is, that the database is messed to a certain degree. So I didn’t notice it because I haven’t been using the public sharing so far. I’d be glad if it would be some config issues - the content of the config file can be seen in my first post.
King regards
Kray
