Notify module emailing with bad link

I've gotten the Notify module partially working on my 4.7.6 installation. By partially, i mean the link that gets sent in the email appears in this form:

http:///index.php?q=node/67#comment-13

and the "To stop receiving these e-mails..." link appears as:

http:///index.php?q=user/69/notify

Yes, that's a 3rd "/" in the URL and, of course, no domain name.

Am I missing something obvious?

Thanks.
