Maps Not Working

Hello,

Maps is not working, even after I’ve added an API into Highend Options > Map Settings
Website is https://santuariodedios.org/ and can be seen in its error-state in the right-hand footer.

I’ve used this theme many times, and this is the first time I’ve come across this issue. I am using the same API Key for every site (around 10 sites) using Highend the same exact way/settings on the back end.

Please help.
