Custom Post Type Cleanup

Description

Custom post type posts are left in the database if a post type is no longer registered (in use).

Plugins and themes can (without you knowing) use custom post types as a way to store data. These posts stay in the database forever if they’re not cleaned up by the plugin/theme itself upon deletion.

There are a lot of plugins that clean your database (by removing revisions, drafts etc.), but I haven’t found one that does a cleanup of unused post type posts.

This plugin provides an easy way to detect and remove posts from post types that are no longer in use. The settings page for this plugin is at wp-admin > Tools > Custom Post Type Cleanup.

Note: The proper WordPress delete function wp_delete_post is used instead of running a direct MySQL query to delete the posts. This way all associated post data (comments, post meta etc.) are also deleted from the database.

Since version 1.2.0 you can re-register unused custom post types for a limited period of time. This allows you to inspect and delete the posts like you would normally (in the wp-admin).

Simple plugin that works great. Does exactly what it says. Saved me a ton of time

Within minutes of installing this terrific plugin, I was able to quickly identify and remove hundreds of old posts in my database from several very old and no longer used custom post types, thereby helping me shrink and streamline a bloated database. Huge thanks to the developer for providing this great tool for free. <3

This does exactly what it says on the tin and does it very well. I love being able to re-register them for a short time just to be sure of what I'm about to do. Great stuff!

I have been looking for a plugin that can clean up these post types, but, most of the 'clean up' plugins only remove basic safe stuff like drafts... I can remove drafts myself! This one gets rid of those old post types that you created for a minute and never could get rid of in the backend. Thank you
