Houzz Icon – Config error

“Was not able to add a config file”

that is the error I get? I downloaded a zip file here: http://fontello.com/

added this to the functions.php:
// Add new icon as an option for social icons
function avia_add_custom_social_icon($icons) {
$icons[‘Houzz’] = ‘houzz’;
return $icons;
}
add_filter(‘avf_social_icons_options’,’avia_add_custom_social_icon’, 10, 1);

// Register new icon as a theme icon
function avia_add_custom_icon($icons) {
$icons[‘houzz’] = array( ‘font’ =>’houzz’, ‘icon’ => ‘ue801′);
return $icons;
}
add_filter(‘avf_default_icons’,’avia_add_custom_icon’, 50, 1);

And then I went to the import/export to import the entire zip file I got from fontello and I get that error…that a config file can’t be created.

What am I missing? :( I’ve contacted WPEngine and they are struggling to find a solution as well.
