Homepage won't update

I’m getting pretty frustrated trying to figure out why the homepage for carsofchange.com won’t update. I have changed widgets around and made many other edits to the homepage, but as soon as I log out of the admin and view the site as a normal user, nothing has changed. I’ve cleared the browser cache multiple times and even deleted the W3 Total Cache plugin to no avail. Changes on second level pages are going through just fine, but the homepage will not change to what I see when logged in as admin on the site.
