"Not Found" on the bottom of Homepage (Canard theme)

Hi,

I am working on this website: https://www.ebersaki.com/

I added posts and pages (some are sticky post, some aren’t). Then I added jetpack plugin to make the featured post appear like the canard theme demo.

After I added jetpack and updated the homepage to look like featured posts/images (it has to be “latest post”, not static homepage) the below text appeared at the bottom of the homepage with a search bar:
Nothing Found

It seems we can’t find what you’re looking for. Perhaps searching can help.

Reading other forums, people say you have to publish posts; but I have already added posts. Is there a way to remove this from the bottom?

Thanks in advance,
