We’ve google maps integrated but you’ve to use their API for the map to work. But it’ll only show on home version 4 which includes google map & only on that home version all of the ads will load on gmap check the screenshot: https://prnt.sc/tc3zo5
Regarding the 503 error I was trying to visit your site but it seems the site is not loading. We’d suggest you to deactivate all of the plugins that are not recommended by the theme & you’ll be able to see what’s causing the issue. A plugin or 3rd party scripts may be causing this issue as it’s loading perfectly on our end.
If you still want to get our help please provide temporary admin access to your site so that we can have a look at it. Post your credentials as private reply.
