Problem with statistic results

Hi,

I've try to auto install WPMU dashboard by auto way but i accuse an error, i've installed it manually and the plugin Hummingbird, but i've now this error :

The performance test didn't return any results. This probably means you're on a local website (which we can't scan) or something went wrong trying to access WPMU DEV. Try again and if this error continues to appear please open a ticket with our support heroes

And no statistic result, can you help me ?
