Maps not showing any more

Is this plugin compatible with WordPress 3.5.x?

Maps are no longer showing with no errors being generated.

Running the shortcode from a page template.
$shortcode = '[effortless-gm view="roadmap" zoom="state" address="'.$address.'" disableUI="on" ]';

I’ve checked and $address is being populated with a valid address.

Doesn’t work ether if I create and embed a new shortcode on a page.

All that’s generated on the page is
<div class="default" id="canvas1" style="width:306px; height:210px"></div>

Wil.
