To uninstall Matomo (Piwik), follow the following steps:
- Remove the Matomo Tracking code from all websites previously tracked with Matomo
- Delete all Matomo files in the piwik/ folder. In some configurations, the piwik/ folder cannot be deleted using FTP. If you can’t delete the piwik/ folder in your FTP, download the script uninstall-delete-piwik-directory.php, upload it to your server above the piwik/ folder, and execute it in your browser. It will delete the piwik/ folder.
- Using a Mysql client such as phpMyAdmin or cPanel, delete the Database storing all Matomo tables
Matomo will then be successfully uninstalled.
