The link you posted was a dead link to a suspended hosting account. I am guessing that you have pages that are being indexed and displayed as a list.
These 2 sections of .htaccess code in your root .htaccess file already take care of this.
# DO NOT SHOW DIRECTORY LISTING
# If you are getting 500 Errors when activating BPS then comment out Options -Indexes
# by adding a # sign in front of it. If there is a typo anywhere in this file you will also see 500 errors.
Options -Indexes
# DIRECTORY INDEX FORCE INDEX.PHP
# Use index.php as default directory index file
# index.html will be ignored will not load.
DirectoryIndex index.php index.html /index.php
.
