Post Loop Problem

Hello,
I could not find this question posted but please let me know if someone has already asked. I am using the Vantage theme. My post loop displays 4 latest posts. Yesterday I published my fifth post which showed up on my post loop. However, when I click the arrow to go my first post, the post loop scrolls but shows nothing.

Here is my site:

Any thoughts?
Thanks.
