What are WordPress dashboard transient feeds and how to clean them?
A transient is a method for temporarily storing cached data in your database, identified by a name and set to expire after a specified timeframe.
To clean up these dashboard transients, you can either use our Advanced Database Cleaner plugin or run the following SQL code (used by the plugin) directly via phpMyAdmin:
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_%'
