Issue with links in forum emails

[phobus]

Is anyone else having a problem with the emails they get from the forum, e.g. for PMs or subscribed thread notifications?

Starting around the beginning of November, the URLs included in these messages are broken. Now they just show the relative path instead of the full URL (i.e., /forums/private.php instead of http://www.project1999.org/forums/private.php).
