If a website bug is not easily solved, first order of troubleshooting is to disable all extensions. Devs don't often think an extension could be causing the problem, but extensions can do wild things to a webpage. I've caught a few bugs caused by extensions this way.
"Hunch #2" in this article is about extensions causing problems. That is what my comment is in reference to, but maybe you didn't read the article.
Sorry but there is no rule that every comment made about an article must be specific to the outcome of an article about troubleshooting. I can comment about other things covered in the article too.
