The document says replace
define('WP_SITEURL', 'http://' . $SERVER['HTTPHOST'] . '/');
define('WP_HOME', 'http://' . $SERVER['HTTPHOST'] . '/');
with
define('WP_SITEURL', 'http://DOMAIN/');
define('WP_HOME', 'http://DOMAIN/');.
The problem is my file reads
define('WP_SITEURL', 'http://' . $SERVER['HTTPHOST'] . '/wordpress');
define('WP_HOME', 'http://' . $SERVER['HTTPHOST'] . '/wordpress');
if i change this, when I go to my domain it displays the bitnami page, however, if i go to domain/wordpress is no longer works!
