I’ve set Theme Options > Blog Style > “Use advanced layout editor to build your own blog layout”. How do I navigate to this “blog” page once I’ve set it to the desired template? How do I navigate to the blog page?

For instance: www.host.com/2015/08/16/our-story/ will take me to a blog single post page, but it’s the wrong layout.

One remedy would be to somehow use a custom sidebar on the single post page.
