In fact, the call of the css looks like this (with <!– comment –>):
<!-- <link rel="stylesheet" type="text/css" href="https://www.mysite.it/wp/wp-content/themes/goodnews48/style.css" /> -->
<!-- <link href='https://www.mysite.it/wp/wp-content/themes/goodnews48/responsive.css' rel='stylesheet' type='text/css'> -->
