Website Layout Broken When I am Not Logged In

Hello,

I am having a problem with the layout of my website when I am not logged in. Viewers were complaining that the website is not showing correctly, I did not see the issue while logged into WP. I logged out and saw that the layout was off. Please review both screen shot links below.

This screenshot shows how the website is configured to look, what it looks like on login

I think it started happening when I loaded some of WPMUDEV plugins. I deactivated most of my plugins to try and fix the issue but that has not help. I have many of your plugins installed so I don't know how to track the issue.

Thanks again.
