Map Doesn't Load

Everything seems to be installed correctly and the api key validates. I have placed the shortcode on a black page. The page loads and I see the search criteria at the top and a blank spot where the map should be. I have seen another post that says there are issues with networked sites and I am running one here.

Thanks for your help.
