Uninstallation

Removing Object Cache Pro is straight forward and can be done using the WordPress dashboard, or WP-CLI:

wp plugin uninstall object-cache-pro --deactivate

These methods ensure that the object-cache.php drop-in is removed as well.

To delete the plugin manually, remove these paths from the file system:

wp-content/object-cache.php
wp-content/plugins/object-cache-pro/
