Does not work

<?php

$columns = array(

In the user fields I throw the same data since they use the same field the 2 tables

Replace Line 53 of ssp.customized.class.php
Original:
$row[ $column['dt'] ] = ($isJoin) ? $data[$i][ $columns[$j]['field'] ] : $data[$i][ $columns[$j]['db'] ];
Replace With:
$row[ $column['dt'] ] = ($isJoin) ? (isset($columns[$j]['as']) ? $data[$i][ $columns[$j]['as'] ] : $data[$i][ $columns[$j]['field'] ]) : $data[$i][ $columns[$j]['db'] ];

It would be better, if you can share your ERROR as well.

Thanks
