Vladimir,
You can add Wordfence to this list of plugins which Plugins Garbage Collector can’t clean out. I used Wordfence on all of my WP sites up until about six months ago when it started to conflict with another plugin I needed, so I deleted Wordfence from all of my sites.
When I run your plugin, I find well over a dozen tables, all with the prefix wp-wfxxxxxx and some of them have thousands of entries and take up 2-3mb! But when I select them all and hit ‘Delete Tables’, I get the following error message “Unknown table ‘luxurywa_wp1.wp_wfbadleechers’ ” which is the first of the tables on the list. If I re-run ‘Search None-WP Tables’ (that should be Non-WP, not None-WP by the way), all the wp_wfxxxxx tables are back again, so the plugin isn’t doing anything to them.
I have tried both v0.9.14 and the latest v0.9.15 with no difference. If you need any further information, let me know, I would be happy to help because this is a plugin that is badly needed!

Hi again,
Just a quick update to my previous post.
[1] You can add a plugin with tables called xxx_ipblcxxxx to the list of tables that PGC can’t delete. I am pretty sure that it is another security plugin that I installed, tried, and deleted, but the tables are still there and can’t be deleted.
[2] I have noticed that when PGC finds one of these tables it quits altogether and doesn’t try to delete any further tables that are checked.
Hope that helps with the debugging.

I had the same issue with Wordfence and trying to delete the 19 tables required to run the plugin.
I would appreciate a way to clean my DB up (sorry if I’m not cool enough to confidently go in the DB backend yet) to optimize things.
Any constructive suggestions would be appreciated too.
To the developer, thank you for creating this plugin!
FYI – I found this plugin, https://wordpress.org/plugins/wordfence-assistant/
One of it’s options is to delete all tables and data in you db.
I ran it and it did. 🙂
