Sorry for my late response..
Remove following lines in functions.inc.php
if(!function_exists('keep_user_values')) {
function keep_user_values($user) {
$userID = $user['pk_i_id'];
$info = Params::getParam('s_info', false, false) ;
$mUsers = User::newInstance() ;
$mUsers->updateDescription($userID, $info) ;
}
}
