Map not rendering

In neither Brave or New Edge does following page render the map; I have to use I/Explorer to get a map to appear, that I can then mark up to report a pothole.

Any clues as to how to fix appreciated ;

With Shields down, there’s no difference.

Possibly a site issue, Firefox and Chrome are also showing no map either.

Thanks; on good old I/Explorer[!!], once I click on pop up (as arrowed) map renders.!

Ah I see, the secure content is more locked down in modern browers. Mixing https/http content is insecure, but older builds of Internet explorer would ignore security concerns and display it.

Its probably a good idea this doesn’t display in newer browsers, the site itself needs to be fixed
