Empty Cache from Admin Panel doesn’t purge Redis cache

Hello there!

I enabled Redis as a cache store with W3 Total Cache, which is working great! I’m hosting my Redis instance in a Docker container with a mapped volume to persist the data.

I’ve run into an issue when I want to purge the cache, page-cache for example, it doesn’t appear to clear the cache.

When I manually clear it and visit some pages, I see the new entries show up.

This is my db-config.php (placed in /wp-content/plugins/w3-total-cache/ini/db-config.php):

<?php

define( 'W3TC_CONFIG_DATABASE', true );

//
// redis config cache
//
define( 'W3TC_CONFIG_CACHE_ENGINE', 'redis');
define( 'W3TC_CONFIG_CACHE_REDIS_SERVERS', '127.0.0.1:6379');

// optional redis settings
define( 'W3TC_CONFIG_CACHE_REDIS_PERSISTENT', true );
define( 'W3TC_CONFIG_CACHE_REDIS_DBID', 0 );
define( 'W3TC_CONFIG_CACHE_REDIS_PASSWORD', '' );
define( 'W3TC_CONFIG_CACHE_REDIS_TIMEOUT', 0 );
define( 'W3TC_CONFIG_CACHE_REDIS_RETRY_INTERVAL', 0 );
define( 'W3TC_CONFIG_CACHE_REDIS_READ_TIMEOUT', 0 );

• WordPress Current version: 6.0.3
• W3 Total Cache Version 2.3.0

This is all on my local machine, as we want to have a POC before we switch the production environment. I hope that I provided enough information, I can provide more when needed!

Thank you for your time.
