This is a network issue.
Open your browser console, in the "network" tab, look for error (should be the last request)
Most possibily it is due to your network configuration, end ing connection (for instance due to some timeout)

but i have got the same message directly on the "projeqtor" computer, without crossing network.

see in attached files screen shot about browser console

I realized the update, family by family, it's passed correctly.

Could you chekc for error in borwser console (directly on the console, not network) or look at corresponding request on network tab and post here response for that request ?

OK, so it is an Error 500, meaning Server error, not applicative error.
Most likely is a timeout.

You can try and change max_execution_time in php.ini to avoid the issue...

just remember me... where is the file php.ini ?

In your php installation.

Under Linux / Ubuntu, it is at /etc/php5/apache2/php.ini
Under Window / Wamp, you can access it through the Wamp console.

ok, i find it, i change value 30 by 300, nothing change
