I'm trying to write a post with multiple pages using the <!--nextpage--> shortcode. In the first page of the post it shows up correctly with the links and number of pages but it won't let me actually preview any of those pages. If I click a link it just defaults back to page 1.
/?p=11367 - is the link for the first page
/?p=11367&page=2 - is the link for the second page but on clicking it just returns to the first url.
I've tried searching for solutions but cannot find any, please can anyone help?
