Jquery grid listview demo page stopped working

Jquery grid listview demo page stopped working

I was intending to use this grid/listview layout for a new site http://view.jquerymobile.com/master/demos/examples/listviews/grid-listview.php, but the demo page isn't working any more (just shows lilsit view and not the grid on larger screens). Have tried it several different browsers and user-agents but it just stays the same. Not very responsive any more!

Anyone have any ideas?

Thanks,
Jonty.
