Deprecated user lookup function since WP 3.3

Noticed that it seems the plugin does not block non-users when searching for them int he DB. This uses a deprecated function on line 337 “get_userdatabylogin($username)”.

Change:
$userdata = get_userdatabylogin($username);

to

$userdata = get_user_by(‘login’, $username );

and that should fix the plug-in.
