There’s supposed to be infinite scroll on my front page. I currently have thirteen posts to display. In Dashboard > Settings > Reading, I have it set to show five posts when infinite scroll is turned off. I have it set to display seven posts when infinite scroll is turned on. Seven posts appear. So, that is working. And this little footer thing pops up if you scroll down to the bottom of the page.
But the actual functionality of the infinite scroll apparently isn’t working because after the first seven posts, it’s not loading the other six. Here is the site explaining Jetpack Infinite Scroll, here.
I believe I’ve done everything it says and I was able to activate Infinite Scroll under Dashboard > Jetpack, so I don’t know what is going on exactly.
