Just got plugin installed into client site. Created map and also tried demo maps. Map attempts to load and then I get gray screen/error: "This page didn't load Google Maps correctly. See the JavaScript console for technical details." With no indication of what or where that is or how it is germaine. I'm under deadline. Was going to upgrade for custom markers but not if this is indicator of ease.

Hello Kate! Thank you for keeping us posted about this issue!

Please make sure you have provided API keys for your Google Maps in Google Maps WD > Options page. In case you haven't, you can use this user guide section to configure the keys: goo.gl/oSocrE

But if you did add the API key and are still facing the issue, please submit a support ticket by forwarding temporary WordPress admin access to your site. You can use the contact form on this page to do that: goo.gl/j72uyK

Also make sure to indicate the link to this forum thread in your message.
Thanks! Have a wonderful day!
