What are WordPress auto-drafts and how to clean them?
WordPress automatically saves your post (or page) while you’re editing it, creating what is known as an auto-draft. If you don’t hit the publish or update button, the post/page remains as an auto-draft, and any modifications won’t be visible on your public site. Over time, you may accumulate multiple auto-drafts that you never publish, which you can clean up.
To clean WordPress auto-drafts, you can use our Advanced Database Cleaner plugin or run the following SQL code directly via phpMyAdmin (the same code used by the plugin):
DELETE FROM posts WHERE post_status = 'auto-draft'
