After enablinhg the theme (‘X’), I get the following message in the dashboard:
We attempted to installed Cornerstone (required by X) automatically, but were unable to. You may need to install [Cornerstone manually]. [Error Details].
The first link takes me to the apex, Welcome screen which explains nothing whatsoever regarding the error, or installing Cornerstone manually.
The second link takes me to the exact same page I am on when I clicked the link.
Where are the instructions for installing cornerstone manually?
