Sorry, the content area was not found on your page

Hi,

I installed the theme and all its plugins and then imported the demo content, I then tried to edit the homepage and I get an error saying: “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 am using Elementor, please could somebody help?

Thanks,
