First of all I love this plugin, just what I was looking for.
Now the bad news....I had been using it for a couple of days, adding post types and taxonomies. Then all of a sudden pages, posts and media stopped showing entries. In other words, when I click on "Pages", "Posts" or "Media" to view all the entries it says Nothing Found. It's showing counts in "published" and "trash" for each post type but not actually showing the entries themselves. I have deactivated ALL plugins and still every time I reactivate Custom Post Types UI it breaks everything.
The only thing that I recall doing even remotely different when it happened was that I started making some of the taxonomies hierarchical.
Any help would be appreciated. I had a ton of work done using this plugin before this happened.
