Infinite SEO: Getting a 404 Not Found Error

I recently upgraded some of the plugins on the site. Prosites and Infinite SEO. Before I tried this the Directory plugin worked fine. Now I receive a 404 Not Found Error.

Do I have a conflict with the Infinite SEO plugin and Blogs Directory. My site is Weddingsocial.net and my site with the 404 error is http://www.weddingsocial.net/blogs/

Any ideas?
