I didn't click the "Install" button after uploading the component into my site then there's error after select Components - Phoca Maps - Maps.
But if click "Install" right after uploading the .zip package, everything's ok.
I think a "Error if not click one of the buttons" is ok.
Superb detailed document makes it easy to put everything in places.
Simple but very, very good looking map after integrating into articles.
