post upgrade to 21.1.7_1, live Traffic Graphing has stopped working

[BISI Sysadmin]

It was working pre-upgrade (21.1.5).  Essentially the widget on the lobby dashboard is now just a white box.  I have rebooted, removed and re-instantiated the widget (with reboots at each stage).

The Reporting -> Traffic page is in a similar state - two tabs (Graph, Top Talkers), and "Nothing Selected" with the pull down for the selection showing nothing.

I have attached a screenshot of the main reporting page

I have several other routers on the same hardware that all upgraded successfully

Where to go from here?

Thanks in advance!

Hi
can you try to clear browser cache, restart browser and check if it helped?
if not, please see if there are any errors in the dev console?

D'oh!

Restarting FF (which has the effect of clearing the cache/cookies on my config) fixed the issue.  I think I was blinded by the fact that all the other updates worked just fine.

BTW (maybe for future use), when you say "errors in the dev console", can you be more explicit?  Would this be the physical console for the unit? or just using ssh to get to the unit and becoming root?

Thanks for the tip!

ok, I will try to be more specific )
in this case I meant the browser dev console
