Bug when adding new friend

[geekbay]

Hi, here is the bug when i add friend nothing occure.
It's because the var ajaxurl isn't good
my site is in:
​http://10.0.0.3/site.com/html/
but

var ajaxurl = http://10.0.0.3/site.com/html/site.com/html/wp-load.php

as you can see there is two times /site.com/html/ it's because

$_SERVER['SCRIPT_NAME'] = /site.com/html/index.php

so here is my patch
