Honestly the best way to integrate custom posts types in 3.1 is to register them in the functions.php without a plug-in, using register_post_type. If you learn its parameters it will be time well spent, affording you a ton of flexibility down the road. The documentation on this function is fairly detailed and Tadlock has a nice article on it as well.
Best advice: trade the plug-in in for some good old-fashioned copy, paste, and tweak.
I’m having the same problem. When I manually enter register_post_type in the functions.php I’m still unable to edit the entries after regaining the post type in the admin sidebar.
Does anyone have a solution for this?
