That's interesting - it may be that your browser has page information cached, and the change of location has confused it slightly. If possible try it on a computer which you didn't use to view your Moodle when it was at the previous location. If it works okay then try clearing the browser's cache on your usual computer. If it's still not right then it may be a DNS issue, in which case it may settle down over the next day or two. If not then you'll have to look at the settings in Moodle and on your webhost again.
