Andrea,
That code has indeed moved. To make the same change as in your other thread, please edit /components/com_jfbconnect/libraries/profile.php . Around line 199, you'll see:
$params = array(
'method' => 'fql.query',
'query' => $fql,
);Update that like in the other post to:
$params = array(
'method' => 'fql.query',
'query' => $fql,
'locale' => 'it_IT',
);
Definitely still test. We had some development with that but it proved to be problematic with some fields (like date mentioned in the other thread). It also hasn't been requested by any other users, so it's not a priority to debug and implement considering the issues it may introduce.
I hope that helps,
Alex
