I also dont have the option of selecting to display a Static Page on the front.ive been into Settings>Reading> etc but no option.
That’s weird since it’s the very first option on the page “Front page displays”. Are you using an admin account?
I also don’t see what the first problem is. On my test I set a static page to be the front page then I edit that page so it has no Title and Content but I don’t see any “nothing found” error.
