I have no idea what caused this, but I have one post that has a sidebar that is way too narrow. The sidebar in my other post is completely perfect. If the settings for the Container and Sidebars is supposed to apply to all of them, why would this one be different?
Okay, I reverted the article back to a version that did not have that issue. I think it happened when I tried to “fix” a link in that part of the article. Thank you so much for catching that! I didn’t realize the font went bold in that section.
