The plugin has many flaws and cannot display properly in any WP-version. Except for the "view" tab all others are missing the tab and by that contain a HTML coding bug which causes any layout to blow up.
Also, the editing form cannot be rendered correctly because of novice coding. TinyMce couldn't be loaded initially, because of the "simple theme" missing in the WP stock edition.
The plugin needs a complete overhaul or should be pulled from the market.
