Ok, thanks, I'll try once more.

Installed nodebb-plugin-s3-uploads, activated it but how do i configure it?

installed nodebb-plugin-import

enabled it then as instructed go to mydomain
http://localhost:4567/admin/plugins/import (or whatever URL your instance lives on)

and get /
admin/plugins/import Not Found

Web sites I have use Apache but from what i can see NodeBB uses Nginx, would it matter do I need any other settings?

Thanks, but the question was not about shared hosting. Talking about 2GB VPS that is running other PHP sites and Webmin.

I have server, running Webmin and few PHP sites, Apache, PHP7 ,Ubuntu. Can I add NodeBB, or it needs separate server?
