@naxxmare, I had a similar issue this evening.
Navigate to %AppData% in Windows Explorer
Create a folder called npm
I have got 3 NodeBB installation on my server. Up to now everything worked properly. But just some minutes ago I changed the 'Site Title" in Settings General to a new title and it affected all installations. And I did it again and again and it affected them all again.
All config.json have a different DB setting (redis number).
I wanted to launch the third site today... so it's pretty urgent.
PS: posted also in Github issue tracker.
It does this even when I am logged out of one of them.
And inside /admin/settings/general the correct settings are kept, but in the header of the forum at / it gets changed everywhere.
Are you using multiple workers on any of the installs?
Yes, I do. Each on a different port.
great! thanks so much for the quick fix! meanwhile I found a quick workaround through restarting everything. will wait with the merge...
