There are two ways to know which version of Piwik you are using:

  • In the top right menu, click on “Help” screen in the menu dropdown. The title of the Help will say “About Piwik X.Y” (X.Y being the Piwik version).
  • or look in the file core/Version.php: you can download this file from your FTP server, inside this file will be the version number you are currently using.
