I am having the same issue that ontguy had. I am using the latest version 0.9.6.3 and wordpress version 3.6.1. Everything works and a subscriber is added to the proper list, I only have one list, when I look in the admin panel under lists and subscribers but the only thing that is weird is the confirming email to me, the admin, when a subscriber is added shows a recent post I made on the website, not the list they joined. The text of the email is below.
[email protected] has subscribed to your list “Halloween Costume Game”
I updated the permalinks when the double opt-in confirming email link to the subscriber was not going to the right page and that resolved that issue. Is this a permalink issue as well? It’s not a big deal as long as everything else works, but I just want to try and fix it.
