Nothing under Host/Dashboard Tab

[RhymeInspectah]

Compilation and install of gingerbase and ginger plugins went well, I think. But I've nothing under host/dashboard tab in wokd interface. Under the host/upgrade tab there are upgrades. However, under wok/settings/plugins management tab there are kimchi, gingerbase and ginger active.
In CLI after wokd launching I've lot of python errors:

rc: 3 error: Redirecting to /bin/systemctl status nginx.service
returned from cmd: service nginx status
Redirecting to /bin/systemctl start nginx.service

Any Idea ? Is it due to python 3.8 ? May I shoud downgrade python ?
Thanks.

I've upgraded psutil. Now no errors after wokd launch in CLI but still nothing under host / dashboard tab in wok web UI.
