One of the more powerful and useful features of WordPress is – Post Revisions. A few post revisions here and there don’t make much of a difference. But the harmless post revisions can turn into a serious nuisance, if they start to pile up.
Due to constraints on database storage limits, many users don’t like post revisions, therefore here we are showing you how to delete them entirely.
#1. Delete Existing Post Revisions
It is simple and super quick. Just run the following SQL query from your PHPMyAdmin.
DELETE FROM wp_posts WHERE post_type = ‘revision';
This helps you not only delete the post revisions but also the existing revisions saved in the database.
