Steps to replicate the issue (include links if applicable):
- Visit https://en.wikipedia.org/w/api.php?action=query&meta=userinfo&uiprop=unreadcount while logged out.
What happens?:
The API says "unreadcount": "1000+".
What should have happened instead?:
"unreadcount": 0, or maybe an error message.
This is supposed to return the number of unseen changes to pages on your watchlist. As logged out users do not have a watchlist, I would expect 0 or an error.
Other wikis report different numbers. For example, https://pl.wikipedia.org/w/api.php?action=query&meta=userinfo&uiprop=unreadcount reports 4 right now.
Are there actually watchlist entries in the databases for the logged out user (id=0)?
