We apologize for the instability of composr.app and appreciate your patience. We are working on the statistics addon and trying to find an optimal way to store and render data. Unfortunately, we have yet to find a solution that can handle the traffic (and therefore, tens of millions of statistical records) of composr.app. We're working hard on one.
If you get any errors about critical_errors.ini being missing, or $FORUM_DRIVER being undefined, after install, refresh the page and it should go away. This should hopefully be fixed in beta9.

Version 10.0.52 is a little delayed as a bug has been brought to my attention but should hopefully be out soon.
