There is a problem with 6.1 in your profile where your friend will not show up. I found this on an other blog and it worked great for me.

Open File /inc/profiles.inc.php
Around line 102 find:
if (!array_key_exists($friend_list_arr['ID'], $aMutualFriends)){
Replace with
// 405MOD - My Friends: if (!array_key_exists($friend_list_arr['ID'], $aMutualFriends)){
Around line 113 find:
}
Replace with
// 405MOD - My Friends: }
You are DONE!


Hopes this works for you. I spent two see more months looking for a fix.
