Message 'zotero.sqlite-journal unable synchronize'
I am using Zotero for a while, but since couple of months I keep getting this message "zotero.sqlite-journal unable synchronize". I have searcherd online, but could not find an answer what this means and how to fix this problem. Can anyone help me? My Zotero is synced with the Yandex.Disk, might this be a reason?
