Hello, I have a display problem. Problem with backend in dashboard “Availability map”

librenms is installed on a debian 12.1

I rebooted the server without resolving the problem


I have the same problem, running Debian 12 as well.
I think there was an upgrade of the php packages just a couple of days ago (maybe even yesterday).

I am absolutely certain the timezone is set correctly in both php ini files. I’ve run LibreNMS without issue for a long time.

I had the same issue and just find out what was the problem.

In the settings of the Availability map widget, set the Disabled polling/alerting to Hide instead of Show :



And Voilà


Looks like someone broke it, should be fixed next update (or run ./daily.sh)
