Redis Object Cache breaks your WordPress? Do this!

Do two things

• Explicitly specify the database of choice you wanna use for each site (assuming you’re running multiple wordpress instances on the same VPS)
  
  To specify the database, do this define( 'WP_REDIS_DATABASE', X); where X is a number from 1-16
• IMPORTANT: Put the above definition AT THE TOP of your WordPress wp-config.php file. Preferably, the first line before even the DB definitions.

Remember the Zen of Python: Explicit is better than Implicit

Enjoy!
