It is a bug of Joomla 3.1.1. Two bracket typos.


To fix it, just modify the file: joomla/components/com_users/models/registration.php

Go to line 109, change the bracket as below.

$query->select($db->quoteName( array('name', 'email', 'sendEmail', 'id')))
->from($db->quoteName('#__users'))
->where( $db->quoteName('sendEmail') . ' = ' . 1);

Go to line 521, change the bracket as below/

$query->select($db->quoteName(array('name', 'email', 'sendEmail')))
->from($db->quoteName('#__users'))
->where($db->quoteName('sendEmail') . ' = ' . 1);

That is all.
