Thanks, my time away was filled with sadness and reflection, but I did get my furnace fixed. It had dropped to about 50 °F (10 °C) before the heat came back.
Anyway, @Cramac should try setting LIMIT_TO_DIRECTORY to false and PHPDIG_IN_DOMAIN to true, both in the config file.
PHP Code:
define('PHPDIG_IN_DOMAIN',false); //allows phpdig jump hosts in the same
//domain. If the host is "www.mydomain.tld",
//domain is "mydomain.tld"
