[wp-pro] Help With Sidebar Problem

[Gary]

I'm not sure what happened because I didn't do anything except add a 
post, but now the sidebars on my site at http://www.farleftrx.com are 
being pushed to the bottom below the posts. This happens no matter which 
theme I choose for the skin--they all push the sidebars to the bottom. I 
also tried deleting today's post and turning off all plug-ins. The 
sidebars are still at the bottom (inexplicably, because they weren't 
that way two days ago.)

Can someone help?

Thanks,
Gary
