Flush Transients


Just like many other plugins offer a feature to flush the WordPress object cache, this plugin allows to flush transients.

Many WordPress sites do not have access to an object cache in their hosting environment, and for those sites transients are the only mechanism for caching data which WordPress natively supports. Being able to clear transients can be crucial for certain use-cases, particularly on sites that do not use an object cache.

This plugin adds a small admin bar menu item where users with the required capabilities can flush transients for the site. For sites not using an object cache, where transients are stored in the database, the menu item also provides information on the amount of transients stored.

Both regular transients and network transients are supported. When using WordPress Multisite, network transients can be flushed in the Network Admin UI.


  • The admin bar entry to flush transients


  1. Upload the entire flush-transients folder to the /wp-content/plugins/ directory or download it through the WordPress backend.
  2. Activate the plugin through the ‘Plugins’ menu in WordPress.


Which users can flush transients?

The plugin checks for a new capability flush_transients. By default, it is granted to any user that has the manage_options capability.

To disable this default behavior, you can unhook the relevant function:

remove_filter( 'user_has_cap', 'flush_transients_grant_cap' );

Note however that in this case you will have to grant the capability in another way outside of this plugin.

When using WordPress Multisite, network transients can only be flushed by network administrators by default, relying on a distinct flush_network_transients capability.

Where can I configure the plugin?

This plugin doesn’t come with a settings screen or options of any kind. You can flush transients via the admin bar menu item.
