Theme Responsive – Full Width Page (No Sidebar)

Hi – I’ve created two pages recently and have selected Full Width Page (No Sidebar). Unfortunately, when I either preview or publish the new pages, information that I don’t want to appear shows up. Example: ” Posted on June 28, 2013 by Flapjack — No Comments ↓ ” shows up and a Comments Section also appears at the bottom of the page. I’d not had this problem when I first created the site and those pages I previously created aren’t exhibiting this issue. I thought the problem might be because it’s a child page, but when I just tried to create a new page which will appear in the menu as a parent page, I ran into the same issue. What do I need to do to solve this issue? My website is http://theadventuresofflapjack.com

This issue is showing up on http://theadventuresofflapjack.com/about-the-author/interviews-with-dan-and-flap/

Please please help!

Thanks so much!
