This is a great plugin; many thanks. My problem seemed to arise when I updated to 3.6.1.
Q: This is not working for one particular page. I have tried toggling on and off several times and updating the page. I have also tried using another theme (Twenty Ten) as you suggested, and still the page name will not show up in the navigation.
Theme: Elegant Grunge
page that will not show up on the navigation: http://www.extended-family.org/screenings-and-reviews/
