Your system's primary IP address appears to have changed

Operating system Ubuntu Linux 12.04.5
Webmin version 1.900 Usermin version 1.741

Hi, I had my host install an SSL certificate for a website on my server, now I get the above warning with a button to “Update incorrect i/p addresses”
I also get this warning
Warning! SSL Certificate Warning
Some virtual servers’ SSL certificates have expired : *************

All my shared websites and the site with the ssl are working but if I try to make a new site it fails

Thanks for any advise
