I chose the site’s header template that is located at /themes/classic/templates/_partials/header.tpl. With the assistance with the hook h = ‘MyCustomNameHooks’ It's possible an individual have produced it with GTM ? It really is realy nice Resource, but it really need to be inserted just after opening tag in all pages. https://ok-social.com/story4281454/was-ist-canonical-tag-an-overview
