After almost 3 years, the unsubscribe link that is tagged onto the bottom of newsletters has stopped working. If you click on one of the links like

http://www.fishhoo.com/cgi-bin/links/subscribe.cgi?action=unsubscribe=anyone@fishhoo.com,

you get Error: The email address: is not subscribed to this list. I know that the addresses are in email.db because if you browse to subscribe.cgi you can remove any of the addresses that won't work by clicking the link.

Anyone have any ideas why this would be happening?

It should be...

action=unsubscribe&email=bla@bla.com

OK, thanks. That's a start. What could have caused the line to change to what I stated before and how can I fix it?
