Installed EasyBlog and can't access settings - everything else is fine

I have a clean install of all the recent: Joomla 3.3.1, EasyBlog, EasyDiscuss and JomSocial. Everything works fine, except, when I go to settings in administrator for EasyBlog, I get an http 500 error (see attached). I have a dedicated server and everything else has been perfect. If you could please provide some advice as I couldn't find anything directly related to this problem - it's releaseyourburden.com. Many thanks in advance,
