I'm using 2.7, which wasn't an option in the version field above, fyi.
I've set my install to show a static front page, which is working. I created another page, just called blog, and set this as my posts page. The page is published, and the slug is simply blog. But if I code a nav item in my header to link to blog (or /blog or /blog/) it doesn't exist. I can hard code the page id and it works fine.
Why won't the slug work? I used this method in 2.5, pulling /blog/ from the permalink, and it worked fine.
Thanks for assistsance.
