# ‘Invalid post type’ breaks backend

 * I updated [http://workio/insight/](http://workio/insight/) to WP 3.3.1 soon after
   it was released and everything worked fine until yesterday night when I tried
   to add a new post.
 * **The problem**
    On every link in the backend in the ‘Posts’ section I get an
   empty page which says ‘Invalid post type’. Only adding a new post brings up the
   Editor and most options, but not the save/publish box. Screenshot: [https://skitch.com/lucahammer/garye/add-new-post](https://skitch.com/lucahammer/garye/add-new-post)
 * I am still able to add new posts through Quickpress on the Dashboard.
 * **What I tried**
    I didn’t use any custom post types and after trying some related
   solutions I found on the ‘Invalid post type’ error, which all failed to work,
   I deleted everything from the wp_posts table except the one post already published.
   The post type of this post is ‘post’. I turned all plugins off. I used the default
   theme. I tried a different browser.
 * After several hours of testing different stuff I come to you to ask for help.
   If you have any ideas how to solve the problem, I would be really thankful. Else
   I will have to ask one of the devs to reinstall WP (I got no server access).
