I am editing the theme Peggi (https://themeforest.net/item/peggi-a-multipurpose-wordpress-children-theme/22094659) over a child theme to make it GDPR compliant. I managed to remove all external resources like google fonts, except one:
<link href="https://fonts.googleapis.com/css?family=Open+Sans:400%7CRoboto:400%7CFira+Sans:500" rel="stylesheet" property="stylesheet" media="all" type="text/css" >
This link has not been enqueued via wp_enqueue_style and I cannot find it anywhere in the code. I do not know where this line of code comes from. I need to remove it anyway.
