'MAMP "Setup Error: Couldn't match environment"

I'm cloning a live WordPress site to my local machine so I have a safe way to redesign it.

I setup the database, updated my URLs, wp-config, etc. but when I try to view the site I get:

Setup Error: Couldn't match environment!!!

I can't find any documentation or explanation of what this error actually means or how to fix it.
