aaPanel_Kern Following the Redis documentation and configuring the “wp-config.php” file for each of your sites, I've added below right before the /* That's all, stop editing! Happy publication. */. Also change the value “0” in define( 'WP_REDIS_DATABASE', 0 ); for each of your site, for example. 0 for site A, 1 for site B, 2 for site C, etc. The issue has been resolved.
Don't forget to select the appropriate supported clients for your hosting and the last line
define( 'WP_REDIS_HOST', '127.0.0.1' );
define( 'WP_REDIS_PORT', 6379 );
// define( 'WP_REDIS_PASSWORD', 'secret' );
define( 'WP_REDIS_TIMEOUT', 1 );
define( 'WP_REDIS_READ_TIMEOUT', 1 );
//change the database for each site to avoid cache collisions
define( 'WP_REDIS_DATABASE', 0 );
// supported clients: <code>phpredis</code>, <code>credis</code>, <code>predis</code> and <code>hhvm</code>
define( 'WP_REDIS_CLIENT', 'predis' );
