I have a real issue with many of my users. The users can be seen in admin panel like this: [Screenshot from 2019-12-12 20-00-31] But when I try to reveal their email address, It wont show anything to me. And also their public profile gives a 404 error. As far as I see, all of these users are alm…

Another thing I notice: If I inactivate, and then activate them, they get fixed!

If a user is inactive for a certain length of time (730 days by default) they are automatically inactivated. The setting is in your dashboard under Settings/Users and scroll almost down to the bottom. That is where you’ll see that. But, it’s not necessary to make any changes for the sake of making a…

No. My problem is not this. The dashboard says the users are activated.

Seems similar to the issue I’m having . Could you check if the affected names have duplicates or ‘very near matches’ in your database? For example user.user and useruser.

Copying the contents to a new table solves these issues. That said, I did see two occurrences of @bartv ’s issue in @hosna ’s database (those were the two d…

Sounds like a corrupt database index. REINDEX TABLE users should solve the problem.

What about the duplicate usernames? I have many same usernames being used for 2 distinct users. The issue is acknowledged here: [图片] Critical Error: changed username, user got broken support That’s an interesting observation! Usernames are effectively case-insensitive, …

That’s probably a side effect of a corrupt index. You might need to clean that up manually before the reindexing works.
