Only 1 post showing on index page

Can someone take a look at one of the blogs I administrate.

https://celebrated-events.com/blogs/

I have used this Tofurios template on several other blogs but on this one it is giving me fits. The index page will only show one post at a time. Archives words fine and will show multiple posts, so will search etc. But no matter what the settings are it only shows one post on the index!

Can someone tell what is wrong?

Thanks!
