No core files deleted. Just pages and extensions and theme.

I am not sure what you deleted. I don't recommend to delete anything in core files of theme

Ok. So there is nothing missing?

Bacause i think i deleted to much after the old theme...

this is not error. Elementor just tells you that you have no templates for page, nothing else. Ignore it

Up in the right corner you see the error message.

I don't see any errors on page. Please, share screenshot of error

I get this warning from Elementor on my page skattehuset.no:

Template File: No Templates for condition > Rehub theme – page.php

What is this, and how to fix?
