Database Cleaner - Frequently Asked Questions
Why Transients are not cleaned up
Transients are frequently re-created by plugins and themes. You will see 0 after optimizing, then on a reload it will be increased again. This is completely normal
Why scheduled automatic cleaning is not working
Scheduled cleaning requires WordPress Cron. If you've disabled WP-Cron or it's not working, automatic cleaning will not work.
Is it safe to optimize database
Data optimized and cleaned by FlyingPress are safe. But it's better to create a backup before running a database optimization.
