I have just managed to fix a similar problem on my site with a hint from wasseem .

I have changed line 1065 of comprofiler.html.php

from
[code:1]<form action="<?php echo cbSef('index.php'); ?>" class="cb_form" id="adminForm" name="adminForm" method="post">[/code:1]

to
[code:1]<form action="<?php echo cbSef("index.php?option=".$option); ?>" class="cb_form" id="adminForm" name="adminForm" method="post">[/code:1]
