Error rendering raw view

I am so not in the mood for this. So after the site taking ages to try to render a history view I decided to just edit the page for the third time myself, but when I did that I got that error that I've been getting lately where it won't render anything at all. No amount of clicking around between edits and views has so far changed anything. Let me tell you how pleased I am to lose one of the most important pages on my site. 

I rebooted the server because it stopped being able to load pages. The Timeline is still gone. 

What do I do? How do I get my page back?
