Am I getting this error because MW is not caching on localhost?

MediaWiki internal error.

Why would you think that "Cannot access the database: Unknown error (localhost)" could be related to caching, instead of your database? Please clearly elaborate on your path of thoughts.

The problem is about the database connection. Check the database settings and be sure the database server is operational. One of the first things MediaWiki does is to cache/retrieve from cache some localization stuff, that's stored by default on database. As you may expect, an error connecting to the database will cause this error.
