After a very difficult upgrade from 1.0 to 1.1 (I must raz my original install and start from full 1.1) I receive an error while I try to upgrade to 1.1.1:
Fatal error: Class ‘ZIPARCHIVE’ not found in /home/ovh/www/piwik/core/Unzip.php on line 28
Note: 1.1 encounter strange behaviors:
Under Safari Mac, sometime data are correctly shown sometime not
Under Firefox Mac, is better but not every time
Whatever the navigator, it’s less fast and smoothie than with 1.0
