<h4>Why use this plugin?</h4>
<p>Over time, WordPress sites accumulate post meta data from plugins, themes, and page builders. When you switch or remove plugins, their meta often stays in the database — bloating tables, slowing queries, and making backups larger. Post Meta Editor and Cleaner gives you direct control over this data.</p>
<h4>Key benefits</h4>
<ul>
<li><strong>Database optimization</strong> — Remove orphaned meta from deleted plugins to reduce database size and improve performance.</li>
<li><strong>Source identification</strong> — See which plugin or theme created each meta key. The built-in source map recognizes 50+ popular plugins (WooCommerce, Yoast, Rank Math, Elementor, Jetpack, WPML, and many more).</li>
<li><strong>Bulk delete</strong> — Delete more meta keys at once. Adjust process speed to avoid timeouts on large sites.</li>
<li><strong>Search and replace</strong> — Update URLs, domain names, or text across all posts. Works with serialized data (arrays, objects) — both values and keys can be updated.</li>
<li><strong>Flexible deletion</strong> — Delete the entire meta key and its values, or clear values only while keeping the key structure.</li>
<li><strong>Safe editing</strong> — Overwrite meta values in bulk, or perform targeted search-and-replace. Ideal for migrations, domain changes, or fixing incorrect product data.</li>
</ul>
<h4>What you can do</h4>
<ul>
<li>Clean up after removing plugins or themes.</li>
<li>Migrate a site and update old URLs in meta fields.</li>
<li>Fix WooCommerce product attributes, SEO meta, or custom fields in bulk.</li>
<li>Identify and remove unused or duplicate meta keys.</li>
<li>Reduce <code>wp_postmeta</code> table size for faster backups and queries.</li>
</ul>
<h4>Important</h4>
<p>Before making any changes, create a backup, as modifications and deletions can only be restored from a backup.</p>

Post Meta Editor and Cleaner by RotiStudio

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


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
