Error when changing home page

Hi there - I seem to keep getting the following error when I try to change over my home page?

wordpress Unable to save due to 1 invalid setting Your theme has 2 other widget areas, but this particular page doesn’t display them. You can navigate to other pages on your site while using the Customizer to view and edit the widgets displayed on those pages.

Hello,

I would be glad to help you, but can you please provide a link to your website and some explanatory screenshots first?

Kind Regards, Roman.
