I just installed Piwik on a Joomla site (www.velascolawyers.com/).
I made the installation manually, by creating the database using the MySql tool in Cpanel and then by installing Piwik with the standard installer.
I didn’t use the Joomla Piwik component because I feel uneasy about having the analytics data in the same site database.
After few days Google Analytics is tracking less than a hundred visits a day, while Piwik is tracking only one or two visits a day.
I think that the Joomla plugin is installing a different tracking code than the one you can find in the Piwik settings panel.
Can you help me understand why.
