A bug fix has been released on the beta version of CardConversationConfirmation.com today.
Adding a new theme while adding or editing a story was causing an error - this was pretty serious as all new users would have encountered this. On experiencing this bug hitting back and trying to add/edit the new story again would work - this was because the theme now existed and so the add theme function causing the error was not running. Some registered users have been doing this in order to add their stories so to those users - thanks for your perseverance and patience.
All registered users have been informed.
