I did a snapshot on my VM just before

Same problem here. Everything was broken and not fully loaded so I couldn't access any menu in the admin config (JS broken in the console)

I had to rollback. Sadly I don't have time now to try again since it was important to keep it accessible.

edit: I'm using the Persona theme.

I understand. However, it's very likely users are the same because almost everyone is connecting via external provider (GitHub mainly)

Hello everyone! I'd like to "merge" one NodeBB forum with all message from 2 categories to a new category into another NodeBB forum (on another host).

Is it possible? Both NodeBB are on the same version.
