Google maps is not able to show this map

I’m getting an error with the map in https://s567822065.mialojamiento.es/map-of-locations-2/

A popup appears telling that there’s been an error shwowing the map and asking me to read the terms and conditions of google maps (https://www.google.com/intl/en_US/help/terms_maps.html)

Nothing has changed in my installation, I guess. I’m running a pinpoint theme, everything was working properly few weeks ago.

Thnaks!
