Description

Hi, your worst nightmare here... :upside_down_face: According to https://github.com/rhubarbgroup/redis-cache/issues/512, I´m trying to enable Redis from command cli, and I get the following error:

[apache@myserver /opt/apache/htdocs/wordpress-site]$ php wp-cli.phar redis enable

This will be fixed as part of #509.

In the meantime consider using phpredis instead of predis as the client.
