ENFOLD 4.3: function for adding own Google font causes error

Hi,

until I updated to ENFOLD 4.3 I used this function for adding own Google fonts and it worked perfectly:

add_filter( 'avf_google_heading_font', 'avia_add_heading_font');
function avia_add_heading_font($fonts)
{
$fonts['Dosis'] = 'Dosis:300,400,500,600,700';
return $fonts;
}

add_filter( 'avf_google_content_font', 'avia_add_content_font');
function avia_add_content_font($fonts)
{
$fonts['Dosis'] = 'Dosis:300,400,500,600,700';
return $fonts;
}

function avia_add_google_fonts() {
wp_enqueue_style( 'avia-google-fonts', 'https://fonts.googleapis.com/css?family=Cinzel+Decorative:400,700' );
}
add_action( 'wp_enqueue_scripts', 'avia_add_google_fonts' );

I use “Dosis” in the theme settings as my headline font – so far, so good.
“Cinzel Decorative” is only used for some other things like quotes etc.

With ENFOLD 4.3 I get now this error message on top of my backend:

Warning: file_get_contents(/www/htdocs/w012345/mysite/mysitenetwork/https://fonts.googleapis.com/css?family=Cinzel+Decorative:400,700): failed to open stream: No such file or directory in /www/htdocs/w012345/mysite/mysitenetwork/wp-content/themes/enfold/config-templatebuilder/avia-template-builder/php/asset-manager.class.php on line 322

Especially the first mentioned path there is really strange: www/htdocs/w012345/mysite/mysitenetwork/https://fonts.googleapis.com/ …

Is the function mentioned above not longer valid?

There seems to be a mistake in using the wp_enqueue_style part of the function mentioned above, because “Dosis” font works correctly at my site, “Cinzel Decorative” does not.

Note:
– I am using a multisite and ENFOLD is installed in a subfolder for a sub-site, if this is important to know for you.
– ENFOLD is the parent theme, I DO NOT use a child theme in this case!

Could you please give me the right function how to add my own Google fonts for using them in the theme settings? Thanks.
