Why does my site whitescreen with content? I am creating a drupal 8 site.  I have only installed two modules so far, Devel and Varnish.

However anytime I try to create an article and save it any page on the site that isn't an admin page is just White screen of Death.  

I have no idea what could be causing this problem.  Why would it cause the white screen?
Drupal 8 is still in beta so things are still going to be rough there. 

WSOD's are usually a symptom of some PHP error being hidden by the web server (many default PHP setups don't advertise errors). The d.o. page on WSODs gives good advice on how revealing these errors and diagnosing the problem.
