That looks like a very old config.php, mine look like this...
#What type of URL rewriting should we be using for pretty URLs? Valid options are:
#'none', 'internal', and 'mod_rewrite'. 'internal' will not work with IIS some CGI
#configurations. 'mod_rewrite' requires proper apache configuration, a valid
#.htaccess file and most likely {metadata} in your page templates. For more
#information, see:
#
http://wiki.cmsmadesimple.org/index.php ... ty_URL.27s
$config['url_rewriting'] = 'mod_rewrite';
#Extension to use if you're using mod_rewrite for pretty URLs.
$config['page_extension'] = '.html';
#If you're using the internal pretty url mechanism or mod_rewrite, would you like to
#show urls in their hierarchy? (ex. htt***.mysite.com/parent/parent/childpage)
$config['use_hierarchy'] = true;
#If using none of the above options, what should we be using for the query string
#variable? (ex. htt***.mysite.com/index.php?page=somecontent)
$config['query_var'] = 'page';
