The page format that you paste seems a browser cache issue after some update on the OnDemand side.
My suggestion is try it in other browser and check if it still happening.
A good tools to trouble shooting is Firebug plugin for Firefox browser, using this plugin it’s possible to check if some file on the page doesn’t load properly :)
