Hello,
Thanks for using XStore.
1) Provide temporary wp-admin access, so we can take a closer look.
2) You need to add API key in settings of Map element – https://gyazo.com/dc0b23cb6c8ef512ecd46f79530baf50

Google map is a paid service, so you must enable billing https://developers.google.com/maps/gmp-get-started and use API key. In another case, you will have the title “for development purposes only”
