Single post pages not loading

For some reason the main page is working correctly, but the single pages aren’t working. Why would this be happening?

For example: http://equalityspokane.org works, but if you click on one of the posts, or this link: http://equalityspokane.org/?p=86 it only half loads. It worked last night just fine, not sure why it would of changed!

Any help would be appreciated!
