I can't get my landing page (latest posts) to show up as a page option in the navigation menu. I am using the Pinboard theme. I just changed the landing page from a static page to my latest posts, but now the page that is titled "blog" is blank and the only way I can access the latest posts is to click on the header image. I want my latests posts/blog to link on the navigation menu. How do I set this up?
