I also get a blank page when I go to the Community Builder control panel via "components" in the admin side of things. The site seems to be running fine, but nothing CB related works now.

Anything I can send to help diagnose why this is happening?

Please make sure that you have also updated any of our add-ons to its latest version as indicated in this table:

What package?

There is only one installable package for CB 2.0.

Yup - never install anything on a live website unless you have previously tested on a backup site and even then take a backup before you start.

The tutorial you read is most likely about CB 1.9.1 which had modules and components packaged together.

CB 2.0 has a single Joomla installable package that you can install at once and it will install everything needed.
