Medical Circle “the_content” Error in Elementor editor…

I am using Medical Circle Version: 3.0.1 theme, When I try to edit home page I get this message, and I can not reach the home page and change anything.

“Sorry, the content area was not found in your page. You must call the_content function in the current template, in order for Elementor to work on this page.” I can not reach the home page.

I read in instructions on how to solve it that you may need to put the following code: <? Php the_content (); ?> But I don’t know exactly what line to accommodate it.

Could you please help me?

Thanks
