Elementor error

Hi,

I have succesfully duplicated my website to another domain name. It uses Astra + Elementor

Everything seems to work – the website is live and such – but I get this error when I edit a page with Elementor: This page doesn’t seem to exist.

It also happens when I open Customizer.

It is weird, because all pages are there and I can also just edit the page itself (just not on front end with Elementor).

Have you seen this issue before and what can I do to resolve it?

I have already deleted cache, I have changed permalinks and both did not help.

Looking forward to see your comments, thanks.
