Try it without the www in the url

update_option('siteurl','http://planforward.net/wp');
update_option('home','http://planforward.net/wp');

Without the www you get an error: Error establishing a database connection
http://planforward.net/wp/wp-login.php

Try adding the urls without the www part first
