This plugin makes all custom fields (post meta) visible in the “Custom Fields” meta box on post edit screens.

Show Hidden Post Meta

As a plugin developer, I create hidden post meta all the time and sometimes I need to see it to debug it. This does what it says it does, and well. Its simple and hasn't been updated for a while, but I'm glad it exists!

PS: If you need someone to take this one over, let me know. I'll keep it tested and updated if you're unable to.

Still works on 5.5

This plugin was designed for the purpose of outputting the meta data associated with a WP post or page so developers and site designers can verify what information is available.
To use this plugin, simply activate then either simply navigate to a post, page or custom post type and then click on the “DPM” link in the toolbar. For those who have the toolbar disabled, setting show_meta=true in the URL will activate the meta display. Example:
<pre><code>http://example.com/test-post/?show_meta=true
</code></pre>
