Comics not showing full screen

Last year I had to re-load my site from backup, and switch to the new ComicEasel at the same time. Something went wrong, and I’ve never been able to show comics full screen after that. I’ve tried fixing it via customizations, but I believe there’s a fundamental point somewhere I’m missing.

https://myhood.biz/ is the site, and the goal is to have the current post take up front page, with archives on the left. I had it that way before I had to restore the site, and it’s been a year of intermittent frustration trying to fix it.
