Matomo Tag Manager provides you the ability to debug your website to test before pushing any changes to live. After enabling the preview, you need to specify the URL to debug and it will open the URL and load a debug console on the entered URL. Example:
If the above debug console doesn’t load for you, please ensure the following conditions are met.
- Check if you are debugging the correct site and the URL you have entered contains the Matomo Tag Manager JS code.
- Check if pop-ups are allowed. When you enter a URL to debug, Matomo will try to open the URL in a new tab and set a cookie. Please ensure that no pop-ups are blocked.
