WordPress website viewing as text only

I’m a newbie at this but I’ve followed the instructions on the link. I created a new dir /wordpress in root
copied the files from /var/www to /wordpress
changed the index file to /wordpress/wp-blog-header.php
Now I try to log in using http://www.thewongsituation.com/wp-admin and I get “The requested URL /wordpress/wp-loging.php was not found on this server.”

I’ve also changed the siteurl in phpmyadmin to http://www.thewongsituation.com/wordpress

Thank you in advance.
