I figured it out!
Open:
Yoursite.com/dolphin/orca/inc/header.inc.php

At the bottom of the page you will see:

$gConf['rewrite']['cat'] = 'group/%s.htm';
$gConf['rewrite']['forum'] = 'forum/%s-%d.htm';
$gConf['rewrite']['topic'] = 'topic/%s.htm';
$gConf['rewrite']['user'] = 'user/%s.htm';
$gConf['rewrite']['rss_forum'] = 'rss/forum/%s.htm';
$gConf['rewrite']['rss_topic'] = 'rss/topic/%s.htm';
$gConf['rewrite']['rss_user'] = 'rss/user/%s.htm';
$gConf['rewrite']['rss_all'] = 'rss/all.htm';

That see more is where you add the pound sign (#)

For mine I had to change:
$gConf['rewrite']['topic'] = 'topic/%s.htm';
TO
$gConf['rewrite']['topic'] = '#topic/%s.htm';

Hope this helps!
