The link properly displays the first ten posts in the series. (my default posts per page in WordPress is ten)
However, when I hit the Load more posts button at the bottom, it starts to process, but does not advance to the next set of posts. (there are seventeen posts in this series) The button also disappears.
I figured out what is causing this. It is the infinite scroll function in the JetPack plugin.
I tried the infinite scroll function for a bit but turned it off because I found it annoying. However, even if you turn it off in the WordPress settings you MUST go to JetPack, click learn more and deactivate it.
