It took me a little work, but I managed to fix the jokes blog. It was a fairly simple problem. I just overlooked the files. When the site was initially published, the main file was index.html. I changed it to index.shtml, but forgot to remove the .html file. Well, I've removed that and it's all better now. In doing that I also found that all the blogs were pointing to archives.html instead of .shtml. Now all of those are fixed as well.
