Adding New Social Profiles Crashes Site

Hello,

I’ve followed the directions to add two new icons to Social Profiles, Yelp and TripAdvisor, but when I add the code to the Child’s function.php, the site crashes after a few minutes. After I add the code, the WP message says the message was saved with the green checkbox. Luckily I saved a backup prior to adding everything so I just revert back to the starting point, but I’m perplexed why the site is doing this.

Enfold Child
Version 4.5.7
I also properly added the two icons (Font: Fontello) into Theme Options > Import/Export (should I have done this even though the icons are already installed by default?)

Here’s the code that I added to Appearance > Theme Editor > functions.php

Yelp
// Register new icon as a theme icon
function avia_add_custom_icon($icons) {
$icons[‘yelp’] = array( ‘font’ =>’fontello’, ‘icon’ => ‘uf1e9’);
return $icons;
}
add_filter(‘avf_default_icons’,’avia_add_custom_icon’, 10, 1);

// Add new icon as an option for social icons
function avia_add_custom_social_icon($icons) {
$icons[‘Yelp’] = ‘yelp’;
return $icons;
}
add_filter(‘avf_social_icons_options’,’avia_add_custom_social_icon’, 10, 1);

TripAdvisor
// Register new icon as a theme icon
function avia_add_custom_icon($icons) {
$icons[‘tripadvisor’] = array( ‘font’ =>’fontello’, ‘icon’ => ‘uf262’);
return $icons;
}
add_filter(‘avf_default_icons’,’avia_add_custom_icon’, 10, 1);

// Add new icon as an option for social icons
function avia_add_custom_social_icon($icons) {
$icons[‘TripAdvisor’] = ‘TripAdvisor’;
return $icons;
}
add_filter(‘avf_social_icons_options’,’avia_add_custom_social_icon’, 10, 1);

Prior to the site crashing, the names never appeared in Social Profiles. Here’s the message I received once it did crash. Once I saw this after the third time, I reinstalled the backup again and decided to reach out.
