I think you may need to double check your dividers in your html. I'm using the fake WP layout too. Hope this helps!
The fake WP 2 layout uses two stylesheets for pink and cutesy - the base (https://eggramen.neocities.org/code/css/misc/fakewp_new/fakewp2_new.css) and the skin (https://eggramen.neocities.org/code/css/misc/fakewp2_skin2.css). It looks like you're only using the skin stylesheet, which is probably the issue.
Congrats on your 5th site anniversary! 🥳
