KML files no longer display

All my KML files with embedded overlays that were generated using Radio Mobile Online ( www.ve2dbe.com/english1.html ) no longer display on the Google map. Only the placemarks display. Has there been a change in the KML file format required by Google Maps?
Please advise.
Thank you!
 

Hi
I checked my maps with KML files, and all work as expected.
Cen you give me direct link to page with your map and KML file

Hi.
I rollbacked my server due to they trying hack it.
And your messages was deleted.

I get your KML file, upload to my server and all is OK.

But my server running on Joomla 6, but yours on Joomla 4.
I can't check on my J4 because I was hacked a few months ago, and I didn't do backup test servers (J3, J4, J5, J6).
Now I only have J6, and J5 but I want to migrate it to J6 too, because it is production servers

Try to migrate to Joomla 6 server and check it.
