acrogenesis on "[Plugin: Leaflet Maps Marker (Google Maps, OpenStreetMap, Bing Maps)] Maps not loading after first map"

so i have this facebook page https://www.facebook.com/ElPolloLocoMexico/app_449435941764268 . So the first map shows the markers but then when you click on a link to another map (Coahuila, Ciudad de México, Nuevo León, or Tamaulipas) the maps are empty and it seems as if google maps weren't loading i tried using bing and it doesn't work either. What could be the problem i've looked everywhere.

Thanks
