I don´t know if this has to do something with the theme, but my Google Analytics code is visible over the header, on top of my page. I used the plugin by dFactory to put the code according to Cookie notice. Then the code became visible in live view on top of my page. When going in the Theme Editor, in header.php, I couldn´t see the code. I don´t know if this is a theme, or wordpress overall issue.
Thank you & Best regards
