No route displayed for some gpx files on my page

[FrankReisenhofer]

Hello all together,

On my webside some routes are shown correctly and for some nothing is shown.

Working example:
https://www.reisenhofer.de/index.php/de/fotos-de?view=article&id=461:hier-waren-wir-unterwegs-17&catid=42:albanien-2023

Not working example: https://www.reisenhofer.de/index.php/de/fotos-de?view=article&id=439:hier-waren-wir-unterwegs-16&catid=41:griechenland2022

Any idea what might cause this? Maybe a cashing issue?

What are your settings for Access-Control-Allow-Origin. See the message in the console at the bottom right on the image.

@astridx : Thanks for your hint. I am not so familiar with debugging webpages..So I did not check the console output in the browser.

I adjusted the .htaccess file like described e.g. https://subscription.packtpub.com/book/web-development/9781784393779/4/ch04lvl1sec28/cors-in-joomla.

Looks like this is solving the issue. No clue why this was suddently necessary :-(.

Thanks for your help.
