This message typically indicates a wrong address or coordinates, or the Google Map key is missing in your Theme Options.
Google requires a key to use their Google Map services which you can obtain free from your Google sites account.
The Google Maps key field is located in different places depending on which theme you are using, but can typically be found in the Theme Options under a Google Maps section.
Using Avada as an example:
- Click on Avada > Theme Options
- Click on Contact Form
- Click on Google Maps
- You will see a field to enter the Google API Key.
In BeTheme, this field is under BeTheme > Theme Options on the global settings at the bottom. Refer to your theme documentation for help locating the option.
See How to Create a Google Maps API Key for detailed steps.
