WAN traffic graph doesn't load on dashboard or Status: Traffic Graph page since updating from Sep 8 snapshot. All other interface graphs load fine. WAN is connected according to Status:Interfaces and traffic is passing fine.

Can you update and try again?

I don't get an error like that on the most current snap in a VM

I'm connected via the internet now and it's displaying normally. I'll check it when I get back on the LAN and update if necessary.

I have this problem on all my interfaces with the latest update.
It worked for a long time, then the DMZ interface stopped showing with this error.
A couple of days ago, all of them stopped working. 
No logged errors.
