Custom homepage not working: 404 Not Found
I would like to change my homepage, and found out how to do so, but when I change it, I get a 404 not found, even though it does exist. I have http://www.yourcorner.org showing All Categories right now, but would really like it to show http://yourcorner.org/pages/homepage/ (which does exist). When I put in "pages/homepage" in the "Enter the url to the page you would like to use as your homepage" box, I get the error. And ideas?
