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.
Maybe it's an old bug already fixed.
'misc' does look like it might be manually redirected via a .htaccess, as we changed misc in v9 to browse in v10?
