What is the URL that you have set for your Canvas URL in your Facebook Application? From the site you posted above, it should be:
aboutme247.com/newdev/
I'm not sure if you have it setup to go to the 'newdev' site, which would be required. If not, then when Facebook loads the 'live' (non-newdev) site, it won't be loading the JFBConnect installation that sent the request. In that case, that JFBConnect won't know about the original request, where the user should be redirected, or what the setting of the "Breakout Canvas" value is.
As for the Breakout Canvas setting, my guess for why it doesn't work is above. The reason we give the option is because the Platform policies specifically -do- allow the user to be redirected away from Facebook. However, that can't be the primary/only purpose of your Canvas. So, we want to notify our users that not every request should be marked as Breakout, or if they are, you should have another purpose for your Canvas page.. showing products, letting users see/navigate the site within Facebook, etc. It's up to you how to utilize your Canvas. We don't want to restrict you by not allowing your users to leave, but we also want to make sure our user's are aware of the Platform Policies.. we know not everyone reads them
