Plugins Garbage Collector


Plugins Garbage Collector scans your WordPress database and shows the tables beyond of core WordPress installation. Some WordPress plugins create and use its own database tables. Those tables are left in your database after plugin deactivation and deletion often. If your blog is more than 1 day old you have some plugins garbage in your WordPress database probably. With the help of this plugin you can check your database and discover if it is clean or not.
Extra columns added to the core WordPress tables could be shown also.

Comming soon. Just ask it. I will search the answer.


I have used optimization plugins to clean up my databases for the last few years, and assumed they cleaned all my tables up. Then I was looking at all the tables via phpadmin and saw I still had lots of errant abandoned tables from when I deleted plugins. This simple plugin showed me which tables no longer have plugins (rather than me guessing and making a mistake) and I was able to remove them with a few clicks. Everything worked perfectly after. Thanks for this useful tool. I hope you will continue to update it.
The plugin works well, just needs to be a little more intuitive. I suggest adding more features that are very welcome for those who have a big old wordpress site (maybe in a "pro" version) such as: 1) search for orphaned custom fields from posts and custom posts. With option to remove them; 2) list with all custom fields used in published posts (organized by post type) with option to remove them; 3) search for orphaned options fields in wp_options. Showing which are autoloaded and with the option to remove the line (if you are sure what it is) or just disable autoload. I suggest "revive" the very old plugin "" 4) option to remove orphaned cron actions (many plugins and themes do not remove their cron actions when they are uninstalled); 5) search for orphaned user fields.
Простой, но удобный плагин. Свою функцию по чистке базы от старых плагинов выполняет.
Nice plugin. Works with WordPress version 5.1.1 and Woocommerce version 3.5.7. No problems. Just removed many old tables from database, tables from deleted plugins. Thanks! It just made my site more responsive and faster.
