Thank you. Here it is. The author avatars are lining up vertically in a single row, rather than a block. Thats what they do at the default sidebar setting of 200. I changed sidebar width to 225, which allows the avatars to render in a block, but if I click on an author avatar in the sidebar, then on a post on his bio page, the single post page shows all the sidebar avatars in a single row. Since this is a development stage website, the only author that has posted articles is me (the bald headed avatars with glasses on cranium)
