KML Tracks are not shown on map

I just did the last update for all ZH OpenstreetMap components - after this update all the KML Tracks are not shown on my maps - before update it was working well.
Any suggestions to solve this issue?
Thank you, Kai

Check browser console for errors.
You can give direct link to your page with map to analyse what problem is.

Up to now I always added the KML-Layer directly in MapDetails and it was working well. Since last update it fails without error message.

Look here: www.arfeld.info/index.php/highlights/eder-radweg - now the map is without track.

But I found one solution by maself : I added a path with the track in "Paths" with the internal kml parser and this is working again.

You can see it here: www.arfeld.info/index.php/highlights/wanderwege

Thank you for your wiilingness to help.

I checked - all works correctly.
As in map definition, as as paths.

Check your browser console.
Look at messages

And if you check.

Your site: www.arfeld.info
And URL for KML: arfeld.info/images

Just rewrite your URL to www.arfeld.info/images

Moreover, in your second map there are 2 call kml file, but only one will be processed

first
var kmlLayer2 = zhomPathParser.kml('images/gpxtracks/via-adrina.kml', pathOpt2);

second
var kmlLayer = omnivore.kml(' arfeld.info/images/gpxtracks/via-adrina.kml ')

and only first will be, because you use internal parser with relative path to file.

The second is blocked by CORS, you can see it in console.

You forced rewrite your site to www.arfeld.info/
Therefore all arfeld.info/ will be blocked by CORS (if you not configure the other)

Thank you very much - I'm still learning in Joomla an different plugins and modules. Your support was very helpful - now I've been able to solve all issues in ZH OpenStreetMap. Therefore I did a small donation...
