Redis status - Unknown

Just finished installing ee for WP with subdomains using Redis caching. Everything is fine with one possible exception. When I go into the Redis plugin’s settings it lists the Redis status as being unknown. Is this normal or have I missed something in the setup and/or configuration? There is nothing in Settings for Redis that allows for any changes. The only other info displayed in Settings is as follows:

Protocol: TCP


Port: 6379

Database: 0

Key Prefix:

I have added the following to wp-config.php:

define('WP_CACHE', true);

define('WP_CACHE_KEY_SALT', '');

And the following is in /etc/php5/mods-available/redis.ini:

session.save_handler = redis

session.save_path = "tcp://"

Of course object-cache.php has been uploaded to the wp-content directory. Object caching may be working but the plugin gives no indication one way or another.

I reinstalled the WP site which change the settings of the redis plugin. It now had an enable button. Matter solved.
