Hi dear “remery”,
The plugin cleans transients but not all of them. It cleans only the browser and feed transients. Here is the sql query used by the plugin to clean these transients:
DELETE FROM options WHERE option_name LIKE '_site_transient_browser_%' OR option_name LIKE '_site_transient_timeout_browser_%' OR option_name LIKE '_transient_feed_%' OR option_name LIKE '_transient_timeout_feed_%'
Are these transients removed from the wp_options table?
Where is the setting/function to purge transients?
Please go to the screenshots here: https://ww.wp.xz.cn/plugins/advanced-database-cleaner/screenshots/
In the first screenshot, you will find “Dashboard Transient Feed”, you can clean it to purge transients.
