No shared roster Link in the webinterface

Hi

i have Problem I activate shared roster in the config. But i haven't a link in the webinterface.

% Used modules:
{modules,
[
{mod_register, [{access, register}]},
{mod_roster, []},
{mod_privacy, []},
{mod_adhoc, []},
{mod_configure, []}, % Depends on mod_adhoc
{mod_configure2, []},
{mod_disco, []},
{mod_stats, []},
{mod_vcard, []},
{mod_offline, []},
{mod_announce, [{access, announce}]}, % Depends on mod_adhoc

What is wrong?
