virtualhost opens /xampp

[hanpedro]

Whenever I open tester.dyndns.org, page opens tester.dyndns.org/xampp.
Here's my httpd_hosts.conf.

<VirtualHost *:80>
ServerAdmin webmaster@tester.dyndns.org
DocumentRoot /var/www/html/tester
<Directory "/var/www/html/tester">
Options Indexes FollowSymLinks MultiViews
AllowOverride None
Order allow,deny
Allow from all
</Directory>
ServerName tester.dyndns.org
ServerAlias www.tester.dyndns.org
</VirtualHost>

I have changed the file name of index.html at /opt/lampp/htdocs.
But still opens tester.dyndns.org/xampp.
