Blog does not display after Yahoo Upgrades WordPress to 2.8.4

Hi,
Yahoo upgraded all their sites and when they did, I can no longer bring up my blog page.

Website Version: Thesis 1.5.1 and WordPress 2.8.4.

Webpage: https://www.selahsynergy.com

Problem: When I enter https://www.selahsynergy.com I get default home page that says
” There’s nothing here.

If there were posts in the database, you’d be seeing them. Try creating a post, and see if that solves your problem..”

If I select the any of the links from any of my previous postings on the right column, the blog is displayed correctly on the left.

If I enter https://selahsynergy.com/?page=575 My blog shows up fine on the left side of the page.

Does anyone know how to change WordPress or Thesis to bring up my blog page?

I have spent a good two days trying to fix this site and I can not get over the last hurtle.

If anyone could help me or point me in the right direction, I would really appreciate it.

Thanks
