wordpress infinite-scroll doesn't load additional pages

I am trying to make my wordpress blog https://www.outgrow.me work with the plugin “Infinite Scroll” to load more posts when scrolling close to the bottom of the page.

It keeps saying there are no more posts, but there really are on pages 2 and 3.

(Additionally, there are 3 loading bars popping up. I’m not sure why)

Thank you so much!
