I had used the contact form on the plugins website to report this issue, but figured I'd post here as well in case there are others having the problem.
I installed this today and for whatever reason I'm not seeing any settings options for this plugin anywhere.
It ended up being Better WP Security's "Turn Off File Editor" option that caused the problem. So once I disabled that feature, I was good to go.
I feel silly for not thinking of this earlier, but thought I'd just point it out in case anyone else runs in to the issue. :-)
