Hello, @barryhynd,
Thanks for your contact,
I have checked your site and checked the console, and I found this issue: https://postimg.cc/G95FKHwD
The issue is with your Google MAP API key. The current URL loading the Maps JavaScript API has not been added to the list of allowed referrers. Please check the referrer settings of your API key in the Cloud console.
Please check the details here: https://developers.google.com/maps/documentation/javascript/error-messages?utm_source=devtools&utm_campaign=stable#referer-not-allowed-map-error
And please try to get in touch with the Google Maps API support.
Best Regards,
PThemes Team.
