Splitting a post/page into multiple pages using <!--nextpage-->

Instructions are simple enough at http://codex.wordpress.org/Styling_Page-Links

  • Enter Text (not Visual) mode
  • Place < !–nextpage–> where appropriate (space before exclamation point so it shows up on this forum)

But it just doesn’t seem to work. What ends up happening is the pagination at the bottom of the page displays correctly, listing pages 1, 2, 3, etc, and the links to these pages seem to work correctly as well, but the content itself isn’t being split. Every page, whether it’s www.example.com/page-title/ or www.example.com/page-title/4/ always shows the same full content.

Can anyone help me out with this? Has anyone else used < !–nextpage–> on their site using Roots?

It’s working here: http://demo.roots.io/layout-test/

Maybe a plugin conflict?
