What to do if an error (red text) is displayed in my Tag Assistant?

If you get a text in red in the Tag Assistant, it means that the tag has detected an error. This may come:

• Either from an ads blocker plugin installed in your browser, as "AdBlock". If you have this type of extension, deactivate it and redo the tests of the FAQ available here. If the tag goes blue or green, it means that it actually came from this plugin and your tag works properly.
  
  
• Or from a JavaScript error due to another module installed in your shop or to your webmaster intervention on one of your theme templates. To know how to detect a JavaScript error and how to solve the issue, go to our FAQ: How to detect a JavaScript error?
