The affected div was the one with id "cpt_info_box".
But really strange, i've deactivated and deleted the plugin, then, after i read your reply i've redownloaded the plugin, uploaded and activated, and now seems that the problem is gone.
What i can say is that on the first attempt, when i had that loading problem, i had no posts published, nor in draft and no pages, links, wp was totally empty. I had only some custom post types defined, but also them were empty. Via functions.php i hid posts and links from the backend, that was i had in wp when i tried the first time tour plugin.
Before reuploading adn reactivating your plugin for the second attempt, i had instead some posts in three of the the custom post types.
So, as i don't know what could affected "post type order" the first time, i reported you what i had in my wp setup.
I hope that this helps you in a someway.
For anything just ask me!
