[buddypress-dev] Issue on bp messagges

[Andrea]

On siteurl -> /wp-admin/wpmu-admin.php?page=bp-messages.php

Error output:

Warning: call_user_func_array() [function.call-user-func-array]: First  
argumented is expected to be a valid callback, 'messages_settings' was  
given in /var/www/htdocs/gorilla.creativenetwork.it/wp-includes/ 
plugin.php on line 311

due to line 75 in bp-messagges.php
add_submenu_page ( 'wpmu-admin.php', __('Messages'), __('Messages'),  
1, basename(__FILE__), "messages_settings" );

messages_settings function seems not defined.

Any help on it?

Regards

Andrea
