CustomPress – Error Adding Custom Post Type Via Taxonomies To Menu

I have created a sample post type and a sample taxonomy using CustomPress. The custom post type supports hierarchy. The option to add a menu item for all of the posts of a particular taxonomy/category is available in the WP Menu configuration and I can see the sample taxonomy/category that I set up. However, when I attempt to add the item to the menu, I’m greeted with the following:

Catchable fatal error: Object of class WP_Error could not be converted to string in …/wp-admin/includes/nav-menu.php on line 73

Furthermore, when I click on the sample taxonomoy/category as listed under the new custom post type menu, i’m greeted with:

Cheatin’ uh?

I promise I’m not trying to cheat. Just figure this out. :slight_smile:

The only other plugin I have running is Membership. This is a single site install and I’m logged in as the SuperAdmin. Any help is appreciated.
