Hi Anna
I followed the helpful guide on setting up your Google Maps API to narrow down the conflict that you seem to be having.
Based upon the error message in Chrome Dev Tools, it looks like possibly there is something not yet set up in your Google API account. The error message directs me to a Google help file.
The current URL loading the Google Maps JavaScript API has not been added to the list of allowed referrers. Please check the referrer settings of your API key on the Google API Console.
Can you check that within your Google account?
When generating your API key, you should whitelist your domain(s) so owners of other domains cannot steal your API key’s usage.
We recommend that you include two urls like this:
*.example.com/*
*example.com/*
Please let me know if that helps. 🙂
Thanks,
Courtney
