It has not been a complete day and RailsBricks 3.1.1 has already been released. It fixes a tiny (but blocking) bug with the Redcarpet gem. The version used by RailsBricks has been downgraded to 3.2.0 (was 3.2.2 in RailsBricks 3.1.0).
You are advised to update your installation of RailsBricks before starting a new project as the Post feature won’t work properly with version 3.1.0.
I will investigate the cause of the issue in more details soon.
