@Joykiller there is no issue setting NodeBB up as root. I always do it like that and later chown the installation to another user. Then I start NodeBB over Supervisoe from that non-root user.
All issues resolved. 😛
I lost my .git file in NodeBB folder and can't upgrade NodeBB. How to return .git?
Use whichever 1.x version of NodeBB you're currently on.
