Theme: Sugar and Spice Sidebar down

Hello,

Not sure what happened by my sidebar is being pushed down. I have had my site for almost a year and this has never happened before. I deactivated my plugins and that did not help. I had many errors when I did an HTML validator check so I deleted my sidebar because many of the errors were from that. I fix any left over errors and the problem still was not fixed. I am not sure what to do and I have been looking on this forum and trying different things. However, I think I need help with my specific site (www.savedbythemommy.com). I will appreciate any help. Thanks!
