Can´t see the map of google

Hi!

I am using a child theme with custom css but the map is not visible. In the preview of the widget is seen without a problem (the problem is not in the API key).
I have tried removing the custom css code and selecting the parent topic and it remains unseen.
The last test I’ve done is to install another theme and if it looks right.

Thanks in advance.

Hello Victor,

I have just checked that page and noticed that there is Expired Key Map Error. Here is its description:

Please feel free to ask any other questions that you might have.

Kind Regards, Roman.
