Settings for Home and Blog pages

Hi Sakin, hoping you can help with this: I am developing this site with Simple Catch. Currently in Settings > Reading, I have "Front Page displays" set to "A static page," and two active pages listed for the "Front Page" and "Posts Page." With these settings my home page looks just like it should, but on the posts page, all it says is, "Not found Apologies, but no results were found for the requested archive." And when I try switching "Front Page displays" to "Your latest posts," the posts page looks like it should but the home page has the "Not found" message on it. Any idea what I'm doing wrong? THANK YOU.
