Unable to use authentication

[NizarBlond]

The following are my wp-config.php settings.

I use Redis on localhost.

define( 'WP_REDIS_DATABASE', 3 ); define( 'WP_REDIS_PREFIX', 'NyTFl' ); define( 'WP_REDIS_PASSWORD', [ 'testuser', '123123' ]); define( 'WP_REDIS_CLIENT', 'predis' ); define( 'WP_REDIS_SHARDS', false );

I've configured SHARED to false because for some reason in object-cache.php you only consider the password inside this loop:
foreach ( [ 'WP_REDIS_SERVERS', 'WP_REDIS_SHARDS', 'WP_REDIS_CLUSTER' ] as $constant ) { if ( defined( $constant ) ) { ...

and while I don't understand why, it is the only trick that allows me to use the auth feature.

However, I get this error:

Warning: strlen() expects parameter 1 to be string, array given in /var/www/sites/mysite/wp-content/plugins/redis-cache/dependencies/predis/predis/src/Connection/Factory.php on line 167

Fatal error: Uncaught Predis\Connection\ConnectionException: SELECT failed: NOAUTH Authentication required. [tcp://127.0.0.1:6379] in /var/www/sites/mysite/wp-content/plugins/redis-cache/dependencies/predis/predis/src/Connection/AbstractConnection.php:131

Any idea how to connect?

NOAUTH Authentication required

Read the FAQ.

I read the FAQ, it states that it supported auth connections. I added:

define( 'WP_REDIS_PASSWORD', [ 'testuser', '123123' ]);

But I don't get it to work.

Ideas?

If you followed the FAQ, then try flushing your OPcode cache. Your wp-config.php might be cached by PHP.
