I had the same issue with a test forum on 0.8.3 no errors for me but the no permission
Thanks for reporting https://github.com/NodeBB/NodeBB/issues/4720
Turned out systemd could not write redis' pid file, hence the crashes/restarts.
The missing category is probably a result of that.
Reinstalled and everything is fine.
Thx, keep up the good work! 🙂
Yeah I saw this, but in fact it's more the way it's showed that I would like 😉 I know it's just presentation but this make it easy to show which category is the most active
@nodeham Thank you for all of the help. I will start a new thread for the next problem I am seeing.
