I try to add the google tag script in configuration > design > script but when I do this, the header of the front end show a white line. This line isn't showed when there isn't the google script. It means that I added the script in the wrong section?
<script type="text/javascript">/* <![CDATA[ */var google_conversion_id =AAAAAAAAA;var google_custom_params = window.google_tag_params;var google_remarketing_only = true;/* ]]> */</script><script type="text/javascript" src="//www.AAAAAAA.com/AAAA/AAAAA.js"></script><noscript><div style="display:inline;"><img height="1" width="1" style="border-style:none;" alt="" src="//AAAAAAAAAAAAAAA"/></div></noscript>
