Current Conditions Stopped Updating
I have had my MM running for about 2 months now and everything was working fine till about 10 days ago. The Current Conditions stopped updating. If I reboot or open the site in my desktop browser the weather conditions will populate correctly with the current conditions but not update. i have look to see if the network is dropping the connection and it is not. Any thoughts?
