Perhaps I'm misunderstanding how this plugin works, but

Perhaps I'm misunderstanding how this plugin works, but I can't get it to show up correctly.

I've turned the "Admin sees full content" to no, for testing, but in my draft (I also published it to see if it had to be published), I can't see the Like section.

My shortcode is:

[pwal id="67817696" description="See the book cover!"]This is content that I'm hiding until you like this page or post![/pwal]

But no Like section shows up at all. Is it possible that there's a plugin conflict somewhere?
