I've been uploading several themes and have noticed that the theme offers two sidebars, but when I go into the Widget module, only Sidebar 1 appears. And sometimes, what is in the Widget interface is not reflected in what appears on the site. It seems like the stuff appearing on the live site is handcoded.
How do I make these work? Is there a special plugin that has to be installed? I looked at the code and it says
/* Widgetized sidebar, if you have the plugin installed. */
I haven't been able to find such a plugin.
Any suggestions? Or should I just not use these themes? They seem to be popular so someone has to be making them work.
