Cannot create new answer's anymore

I was able to create a question and an answer on my multisite install but now when I click the new answer tab from the admin panel, I get to blank page with nothing happening. I'm using the london live theme. I had them my login installed but saw where somebody else had an issue with that plugin. Deactivating the plugin didn't solve my issue. You can see the new answer page at http://www.411forfathers.com/wp-admin/post-new.php?post_type=answer. I could really use a hand with this.
