leotheme Leo Elements theme editor impossible to access

[DevQuent]

Hello,

I'm currently having a problem with Leo Element. A short while ago, I could access the theme editor without any problems, but today, without having touched the code, when I try to click on any “Edit with Leo Elements” button, I systematically get the error “Sorry, the content area was not found in your page. You must call ‘the_content’ function in the current template, in order for LeoElements to work on this page.” and I don't understand why and how to fix it.

In the screenshot, it's the displayHome of a profile, but the error is the same for any element.

Do you have any clues? Or examples that might cause this?

Thank you in advance for your help.
