Blog Page 2 Not Found

On my site at TudorCoaching.com/blog, the first page and all of the posts show up just fine. However, I have additional blog posts on the next page which do not show up. When I click onto page 2, I only get “page not found”. I can access the additional blog posts through their url, so I know they are there, but there is something keeping visitors from being able to access them by scrolling through the blog. Please let me now how I can fix this. Always appreciative of your help.
