I got it to do what I needed. Glad that's over with.

This plugin escapes a one star rating only because it’s the better of the 2 wikipedia embed plugins I have found. If you only need to embed wikipedia content on a single page, you’ll probably do fine with it. In my case I needed to used it on numerous pages in a single site, and I’ve had to put way too much time in to make it work.

On both sites I have it installed in, I’ve had to go into PHPmyAdmin and delete tables to make the plugin settings update. The developer has been completely unresponsive to attempts to get support.
