Deactivating Google Fonts

Hi There,

Although we followed all advices here at the forum, there still is the font Roboto loaded from Google server: http://bruegger-legal.com

1. We downloaded Open Sans and installed it locally as suggested.
2. We set fonts to standard and Arial.
3. We added the following code to child theme’s functions.php

/* Google Fonts deaktivieren */
add_action( 'init', 'enfold_customization_switch_fonts' );

function enfold_customization_switch_fonts() {
	global $avia;
	$avia->style->print_extra_output = false;
}

How can Roboto still loaded?

Thanks in advance.
