If you remove Vanilla itself, it seems to be okay.
npm rm nodebb-theme-vanilla
Can't seem to get the group membership working on vanilla.
Is there any particular reason it is missing ?
I mean this:
@hek is your vanilla up to date?
npm install nodebb-theme-vanilla@latest
Vanilla seems to not have those, made an issue https://github.com/NodeBB/nodebb-theme-vanilla/issues/34
