    Hello,
    when i enable the cache via GUI settings it says:

    Status: Not Connected
Client: PECL Extension (v3.0.0-rc1)

    I can connect to the unix socket with redis-cli but it won’t connect with the plugin.
    Settings in wp-config.php i added

    /** Redis Caching Settings */
define('WP_REDIS_PATH', '/data/sockets/redis/redis.sock');
define('WP_REDIS_SCHEME', 'unix');

    when i disable the cache

    PHP Warning:  require_once(/web/wordpress/wp-content/object-cache.php): failed to open stream: No such file or directory in /web/wordpress/wp-includes/load.php on line 482

PHP Fatal error:  require_once(): Failed opening required '/web/wordpress/wp-content/object-cache.php' (include_path='.') in /web/wordpress/wp-includes/load.php on line 482

    the object-cache.php is indeed in the wp-content folder with permissions 644

    I don’t know how to troubleshoot this any further, any help is appreciated!

    The object-cache.php is loaded automatically by WordPress, so I assume the PHP warning you’re seeing is file permission related error. I’d suggest you ask your hosting provider for assistance with that.

    Regarding the Redis connection, could you post text from the “Diagnostics” section below the Redis server list?

    solved.
    the settings in the wp-config.php were added to the end of the file, but had to be defined earlier.
    thank you for your time!

    @jookkoo: Your using the default credentials. Can you verify them by executing this command via SSH on your server?

    
redis-cli ping

    Looks like Redis Server is not installed on your sever.

    Now, Settings-Redis it’s display as below.

    Status: – Connected
    Client: – Predis (v1.1.1)

    PHP Version: 7.0.13
    Multisite: No
    Redis: Not Found
    Predis: 1.1.1
    Status: Connected
    Client: Predis (v1.1.1)
    WP_REDIS_HOST: “127.0.0.1”

    “Redis” only refers to PHP’s PhpRedis extension. I’ll make it more clear with the next release.
