What are WordPress revisions and how to clean them?
WordPress stores a record, called a revision, of each saved draft or published update. This feature allows you to track changes made to your posts and pages over time. However, accumulating too many revisions can lead to unnecessary overhead in your WordPress database, consuming space and making your site sluggish.
To clean up these revisions, 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_type = 'revision'
