It's called wp-category-posts-list... here's the link.

It says its compatible with the latest version of WordPress, but for some reason I can't edit any of the settings, accept for global settings.
Here's what it looks like when I try to edit parameters within the plugin: http://s12.postimage.org/kjfz8ytwb/error1.jpg
As you can see, I'm getting text instead of drop-down menu or check-box options.
Could anyone try downloading it and tell me if it works for them. Or even better, find a solution for why it's not working for me?
