Problem displaying list

When I use the shortcode with no parameters, it works fine. When I enter my custom taxonomy, it doesn’t display. I saw this in the FAQ as a possible culprit:

You set public => false when you registered the taxonomy. It needs to be true: public => true

But where can I go to change that? I set up the taxonomy using the Custom Post Types plugin and can’t for the life of me figure out where to see what the public setting was originally.

The odd thing is that I know it’s doing something because it sticks my sidebar in the main area, so the columns are having some affect on the page still, it’s just not displaying the information. Thoughts?

Thanks,
Janell
