Hi Edward,
Thanks for the response!
You got it: Comments enabled on the Child Theme only.
I’ve developed a plugin to handle some custom post types, automatically set themes, generate static pages, etc. I’m at least a little savvy to plugin mechanics.
Any tips you can provide would be greatly appreciated – thanks again!
Gah – figured it out.

The folder mu-plugins belongs in wp-content, not wp-content/plugins.
