I'm playing around with four free themes. At first I was working with Expound theme and I was trying for an hour to create a page and have it appear on the menu bar. I could not do anything to get it to work. So I switched themes and viola! The pages I made showed up in the menu bar. In three of my four themes no pages on the menu bar. In Twenty Twelve theme all my pages show up perfectly as I intended. What gives?
