Homepage saying “the page you requested could not be found” despite having a page set to the same url

The homepage of my WordPress website is saying: “nothing found, the page you requested could not be found”. I have a page that’s set to the same url, implying it should be the home page.

It was working fine yesterday until I clicked “posts”, and i think it screwed up something. I already tried setting the home page to the static page I want it to display in the read settings and nothing happened. What’s going on?

Edit: fixed!
