I found this link
http://piwik.org/blog/2011/04/piwik-1-4-released-html-reports-beta-ipv6-support-better-campaign-tracking/
but the zip downloaed is for version 1.5.1 not 1.4
i need an older version of the latest.zip because in version 1.5.1 i can not add new users and the default widgets are missing all
i installed version 1.5.1 for 6 times with the same bug
thanks for any ideea
