[Gelöst] Url issue

Background of the issue:
I am working on a site under development and trying to adjust the translated page URLs using WPML. I followed the guide provided to change the URL (slug) in the translation.

Symptoms:
After changing the URL (slug) in the translation, the page now shows a 'Page Not Found' error.

Questions:
Could you please check why the link is broken after updating the slug?
Can you guide me on how to fix the 'Page Not Found' error properly?
