Top devices / interfaces - Problem with backend

Help
1

Suddenly (18/8) my Top devices and top interfaces stopped working.
They just show: “Problem with backend”

Other widgets (alerts / logs) were also empty.
As it was time for a Jessie>Stretch update, I migrated DB/RRD/Config to a new install.
Alerts and log were again populated, pollers works etc, but top devices/interaces stills shows “Problem with backend”.

Nothing in /opt/librenms/logs
Other RRDs are populated and updates without issues as far as I can see.

EDIT: Running ./daily.sh fix some widgets. At least Alerts/Eventlogs ones.

Some widgets are fixed by running the daily.sh and getting to g3a6f143 but not all.

Same problem here. Top Devices/interfaces shows backend problem. Even after running daily.sh. Three diff installs with same problem -

Overnight, the issue fixed itself. Did run daily.sh and had several reboots before, but didn’t get to test the link above.
Cannot confirm what did the trick, but all seems to be working again.
