I have checked your Website now - You have not added your IP in IP restriction Tab - Google Cloud Console.
To add that: Login to Google Cloud Console :
- From the Left menu, go-to
API & Services > Credentials and click on Create Credentials.
- Create a Key named
IP Key and under the IP restrictions tab add your IP Address
- Save all the changes and login to your Foodomaa's Admin Panel.
Admin > Settings > Google Maps and paste your both keys here.
- Google APIs take 5-10 minutes to reflect the changes on your website.
From the screenshot you sent, it seems your IP Address: 18.104.22.168
Please refer to the following documentation ;
