Inspired by this tweet, I’ve decided to give WP-Sweep a try:
WP Tavern: Clean Up WordPress with the New WP-Sweep Plugin http://t.co/001IncpTgN
— Alex (@chemik3r) March 1, 2015
WP-Sweep is a new WordPress plugin which only uses the official WordPress API to delete and clean up orphaned and unused data.
I’ve given it a try on my personal blog and it worked flawlessly. Unfortunately I’ve forgot to write down the exact percentages on what could be sweeped and saved but I have now a good feeling that at least my > 3000 blocked spam comments are finally gone 🙂
Don’t forget to backup your data, before you try this!
