Upgrade StorageLost library
When I logged into Zotero today, my library was mostly missing. Presently, only 149 items appear in my library even though thousands were in it last week. My local Zotero folder has thousands of subfolders, one for each item, from which I optimistically conclude that no data has been lost, but an indexing issue has occurred. A Zotero.sqlite file is present, though I cannot directly open that sqlite file with Zotero. I upgraded my storage just in case, but that does not solve the problem. Please advise. Thanks. Ray
If you don't remember doing that and think you might have left yourself logged into Zotero on a shared computer, you can change your password, delete all Zotero client keys from your key settings, and set up syncing again on your own device.
