@AOKP thank you, thank you, thank you! Did this and was able to run NodeBB without issue.
@julian I was curious about that, as I had no issues with a fresh install yesterday.
@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.
Update:
All issues resolved.
Re-setup everything.
