strange-little-town theme conflict with wp-super-cache


It seems that strange-little-town theme’s single page has some conflict with wp-super-cache. The theme’s single page layout would be completely misaligned under wp-super-cache, but the index page is ok. Example:



My wp-super-cache setting is not to show cached pages for log in users, so when I am logged in, the single page layout is perfect, when logged out, it’s misaligned. I have tried clearing wp-super-cache and it’s still the same.
