"No crop selected"

Hi trying to use this plugin to go with the Hueman theme I have, but no matter what I do I get the “No crop selected”. I’ve done a bunch of things recommended in this support topic, but no difference (debugging on/off, etc.).

As a newb, are there settings in other parts of my WP install that need to be looked at?

Thanks,

Shawn
