The Debug Mode console is not displaying



If you’re not seeing the Debug Mode console on your website, it could be because:

  • You haven’t activated the Debug Mode console in the Validation Dashboard
  • The Criteo OneTag is not implemented yet
  • You are missing the Criteo loader or there is a syntax error in the loader that is preventing Criteo OneTag from being loaded



  1. To activate the Debug Mode console, click on the ACTIVATE DEBUG MODE button in the Validation Dashboard. Read How to use the Debug Mode console for more information.

  1. On every page you’ve implemented the Criteo OneTag, make sure the Criteo loader is declared by following these steps:
  • Open the Developer tool in your browser of choice by pressing F12 on your keyboard
  • Click on the Network tab in the Developer tool
  • Refresh the page (Crtl+R)
  • Filter or search for the Criteo loader by typing "ld.js". For example, this is a correct Criteo loader call in the Chrome Developer tool:
  • If you can’t find the ld.js, make sure this part of the tag is correctly implemented in your source code. Find out more here.
