Why the extensions disppeared?
I used the Zotero as usual one day and found that there was no extensions. The Add-ons manager has nothing and i shows that "You don't have any add-ons of this type installed". Nothing left including the Word plugin. How should I solve the problem now?
Upgrade Storage
Try going to your Zotero profile directory, deleting extensions.json, and restarting Zotero.
Windows 10 and Zotero 6.0.10 . Report ID is 156222337. But this problem isn't included in the report.
If not, reinstall Zotero from the download page.
If so, close Zotero, move the "C:\Users\\AppData\Roaming\Zotero\Zotero\" folder to a temporary folder on your desktop, and then restart Zotero, and see if that helps.
What should I do next? Login and download the extensions again? And what about the folder moved out just now?
You'll need to reinstall any third-party extensions.
I've just tried solving it. I move the "C:\Users\\AppData\Roaming\Zotero\Zotero\" folder back, and only move the "prefs.js", "prefs-1.js" files out and restarte the Zotero. There are still no user data as well as the extensions. Then i put the "prefs.js" back and it works. The things missing comes back. I think maybe the problem with the file “prefs-1.js”.And I wonder why this file generated.
