[Closed] Main Language is not loading

Hintergrund des Themas:
We moved the site to our server, and since then the main language, which is AT, is not loading. It loads hidden link instead of hidden link. I only changed the memory limit. On the old server, everything was working as expected. On the hidden link, the page ID is the same as the /at/ version. I don’t know where to edit the .com home site. It's very important for us to load hidden link at the start, not the hidden link.

Die Symptome:
The main language (AT) is not loading correctly after moving the site to a new server.

Fragen:
How can I ensure that hidden link loads as the main language?
Where can I edit the .com home page?
BTW its an Elementor site...
