The twig function

{{ yc_track_user(content.id) }}

is calling the template "track_user.html.twig" from the EzSystemsRecommendationBundle.

This template uses the following javascript code:

_ycq.push(['_setAccount', 'XXX']);

This code is misinterpreted by Google Tag Manager and analysed as an error because it is confused with the Google Analytics tracking code, which is:

gaq.push(['_setAccount', 'UA-XXXXX-X']);

If the following code also works for eZ Recommendation, I think it's better to use this one in the "track_user.html.twig" instead of the current one.

_ycq.push(['_setMandator', 'XXX']); 

Thanks.
