Permalink Structure – Posts

Hi All,

I’m having an issue with one particular post, who’s URL is http://www.justaguy.us/drinks/hump-day-hangout/

This particular URL returns a 404.

A similar post with URL: http://www.justaguy.us/music/the-greatest-generation-by-the-wonder-years-album-review/
seems to work just fine.

Any ideas on why this would occur? Is it possibly due to the permalink structure updating after the post was published?

Any help would be much appreciated. Thanks!
