Won’t show older entries

When I click on “older entries” it shows the same three entries on every page. I’ve checked all of the settings, but I find nothing that would fix it. In case you want to check it out, it’s here: http://www.girlstartingover.com. I’ve been working with WordPress for years, but this is the first time with this version (the last I used was 2.7). I’m also using a theme from WooThemes (http://www.woothemes.com) that gives me a section for theme options only, but the only options that gives me is how many entries on the main page.
