These two lines have nearly the same meaning. They define a struct called post, aka struct:post. When you define the same thing twice in a module, Racket complains. I doubt this ever worked.
title : string? body : string?
I don't understand these two lines. Neither title nor body are identifiers you have defined in your module/program. (You have fields named that, but that's all.) The ':' isn't a syntactically legitimate token.
