I’m going to guess that this is not a highly popular plugin, although it does exactly what I want, so I’m kind of disappointed that I can’t get a resolution to my issue. I posted a question 3 weeks ago that has not been answered by anyone.
That did it. Thanks a lot. I had tried adding the get_sidebar() before, but I didn’t know about changing the class of the div, so instead it made the sidebar show up at the bottom of the page.
