Warning: Missing argument 3 for avia_woocommerce_gallery_thumbnail_description()

How can I fix this?

Warning: Missing argument 3 for avia_woocommerce_gallery_thumbnail_description(), called in /www/htdocs/w00d6ce9/xxx.com/wp-includes/class-wp-hook.php on line 288 and defined in /www/htdocs/w00d6ce9/xxx.com/wp-content/themes/enfold-child/functions.php on line 46

I have already disabled all plugins, I added this code at the buttom of the functions.php
global $woocommerce;

if( version_compare( $woocommerce->version, ‘3.0.0’, “>=” ) ) {

function avia_woocommerce_gallery_thumbnail_description($img, $attachment_id, $post_id, $image_class ) {
return $img;
}
function avia_woocommerce_post_thumbnail_description($img, $post_id){
return $img;
}

}
and I have no Updates available. You are running the latest version! (4.5.2)

Any Ideas?
