I'm using Ver. 2.1.2 with the Tiga-06 template. I've tried everything I can find to hide child pages in the sidebar "Pages" widget list. No go.
When I go back to the default sidebar I can use the "depth=-1" attribute and it works just fine. But not with the widget. I've tried using the "exclude" attribute, I've tried the Navigo and Fold Page List plugins. No good.
