On version 7.911, my WAN IP Address changed via DHCP and did not reflect the change inside of WebAdmin. If I SSH into the box and run 'ifconfig' the correct IP address appears. Refreshing the page does not resolve the issue as well. I also noticed I stopped getting e-mailed reports as well.
Problem still exists after a reboot. Upgraded to 7.912 and the issue still existed! The IP address appears to be stuck at the IP address I had when I first did the install. 'ifconfig' shows the current address without issue.
