We'll create fresh WordPress site with Listings Post Type Enable installed. You have 20 minutes to test the plugin after that site we'll be deleted.
This plugin is a very simple one. All it does is add a custom post type called ‘listing’ in the wordpress administrator’s area.
It also adds a custom taxonomy called “Listing Category” and custom taxonomy (non-hierarchical) called “Listing Tag”.
Furthermore it add a custom widget which shows the latest listings from the Listing Custom Post Type posts.
The plugin is in English but it can be translated.
