Problems with tokens
The unsubscribe, view in browser, and forwarding tokens I placed in the message all take the recipient to the user registration page.
In the received email, the URLs associated with each link are as follows:
(unsubscribe) unsubscribe.php?id=M0BAX1BNX1NFUF9AQDFAQF9QTV9TRVBfQEAtMQ==
(view in browser) archive.php?id=M0BAX1BNX1NFUF9AQDFAQF9QTV9TRVBfQEAtMQ==
(forward to a friend) forward.php?id=M0BAX1BNX1NFUF9AQDFAQF9QTV9TRVBfQEAtMQ==
When you click on those links (or paste them into a browser address field) you are forwarded to users_login.php?accesscheck=%2Fpmessenger%2Fforward.php%3Fid%3DM0BAX1BNX1NFUF9AQDFAQF9QTV9TRVBfQEAtMQ%3D%3D
My user list was imported through PHPMyAdmin, if that makes a difference.
