Fresh install of easyengine v4.0.6 on Ubuntu 18.04. All seems to be working ok, but every time I restart a site it shows the following message. Site is working but the no DB error is strange.
sudo ee site restart www.mydomain.com
Restarting wwwmydomaincom_nginx_1 … done
Restarting wwwmydomaincom_php_1 … done
No such service: db
