36gianni36 on "Minotar"

Hi,

I wanted to add minotars as default avatars and added this in my function.php

if ( !function_exists('fb_addgravatar') ) {
function fb_addgravatar( $avatar_defaults ) {
$myavatar = "minotar.net/avatar/{$username}/60.png";
$avatar_defaults[$myavatar] = 'minotar';

return $avatar_defaults;
}

add_filter( 'avatar_defaults', 'fb_addgravatar' );
}

How do I fix it?
