When Piwik displays an error message An error occurred: Cannot connect to the database this means that Piwik was not able to connect to your Mysql database.

To solve this problem you can:

  • Contact your system administrators and ask them to verify that the Mysql server is up and running
  • If your Mysql server is up and running, maybe the username or password used to connect has changed? To update the Mysql connection information, edit your configuration file config/config.ini.php to view and edit your connection details.
