Archiving Error On Main Page

My site is realxpac.com.

It is set (by default) for the top 10 posts to show up on the main page and then it will start archiving them. It’s a new site and I am now on the 11th article. However, with this theme (Gossip theme by elitethemes.net), when I post the 11th article (and any after that), the text of the articles on the main page start going all the way across the main page and the right sidebar goes below it.

As you can tell with the site now, the sidebar is where it should be and everything. However, I only have 10 articles so it’s not archiving them on the main page yet. When I post the 11th article and it starts archiving the older entries, it pushes my sidebar to the bottom of the site and screws up the whole format stretching the story summaries all the way to the right.

Any idea why and how I can fix it?

Thanks,

Chris
