Hi. Temporarily remove the robots.txt file from realwebhost.net and then PhpDig should crawl it. Some tweaks need to be done when PhpDig reads the robots.txt file, as it's too restrictive now, but there isn't a list of tweaks ready.
The deal with the Mansfield site is that PhpDig won't follow the redirect. To fix this, change define('PHPDIG_IN_DOMAIN',false); to define('PHPDIG_IN_DOMAIN',true); in the config.php file, and also make the change listed in
this thread.
