I think I found out the problem… but still no solution :)

Turned off all plugins – no luck
Updated theme – update overridden solution to previous question I asked, but clicking the link did open the accordion and scroll to its content. After changing that line of code, tooltips still didn’t show so I searched and came up with this topic. When I changed those 2 lines of code – tooltips started working, but clicking the link stopped toggling the accordion open and scrolling to content.

Is it possible to have both? :)

This is my child-theme functions.php:

<?php

/*
* Add your own functions here. You can also copy some of the theme functions into this file. 
* WordPress will use those functions instead of the original functions then.
*/

add_filter( 'avf_google_heading_font',  'avia_new_add_heading_font');
function avia_new_add_heading_font($fonts)
{
$fonts['Lato'] = 'Lato:400,300,300italic,400italic,700,900:latin,latin-ext';
return $fonts;
}

add_filter( 'avf_google_content_font',  'avia_new_add_content_font');
function avia_new_add_content_font($fonts)
{
$fonts['Lato'] = 'Lato:400,300,300italic,400italic,700,900:latin,latin-ext';
return $fonts;
}

function add_subset_func($fontlist) {
	$fontlist .= "&subset=latin,latin-ext";
	return $fontlist;
}
add_filter('avf_google_fontlist', 'add_subset_func');

Still no luck

Thanks, it worked :)
