I have tried to install two different custom taxonomy creators in order to have the sidebar show up only on pages labeled under that. I am trying the "Simple Taxonomy" plugin right now, because I saw it recommended somewhere in this forum. I created a taxonomy, and only one term under it, then labeled around 30 pages with that term. But with this plugin and the previous one I tried, when I check the Custom Taxonomy box under LEFT sidebar: Display on: , nothing happens. I have none of the other boxes checked.
I am using Atahualpa 3.7.3 and Wordpress 3.3.1
