+Freeside self-service:
+
+If you are using signup or additional package order with the API-provided
+package selection HTML (as in the services_new.php example), make sure the
+regular Freeside self-service is installed on the same server as the wordpress
+site. Make sure the Freeside configuration setting
+"selfservice_server-base_url" is correct and matches the hostname used to
+access the site, including https:// if using (which you certainly should!).
