Post link Server Error

Hello,

whenever I click a news article on my site it redirects me to here:
http://www.thenerdcabinet.com/gaming/gaming-news/the-walking-dead-game-sells-millions/

If you click the link it says it is a server error, this has been happening since the latest update, are you able to fix it immediately?

It is happening all over my site at: http://www.thenerdcabinet.com

Many Thanks

Joey Hancock
