I was going to make a new topic, but I'll post it here instead, as this is the same issue I'm having.
I'm on a laptop currently, using the Windows client, Windows 7 x64, Owncloud client version 2.3.2 (build 6928) my friend hosts the server. It does the same when I use my desktop PC. This has persisted through a couple of updates to both my client and the server. We've tried reindexing, it didn't help. I'll ask what version his server is on when he's next around. (Edit: 10.0.1)
Issue: Whenever I try and delete or change files from in certain folder, C:\Users\Visi\ownCloud\References\Images\Food\Sweets I get "file deleted from server" errors and syncing stops. The problem is just with this one directory.
I'm aware the images were deleted, I just deleted them. On the next sync Owncloud scans, notices anything I removed or changed in this specific folder, tries to re-download it, discovers it's gone from the server and absolutely freaks out with "File Removed from Server". It never finishes syncing because it's too busy worrying over the supposed errors. The image below is the result after I just attempted to remove the whole thing, but it locks up even if I remove just one image. I can't even scroll down as the window wasn't designed to display that many error messages.
Would like a fix for this... Can supply more information if needed.
