I am having this same problem. I used the code in your FAQ but it’s not working.
I think maybe it’s something with the redirect function?
When you click on the forgot password link on my site it shows this in the URL bar:
https://team.evermark-lnl.com/login/?redirect_to=https%3A%2F%2Fteam.evermark-lnl.com%2Flostpassword%2F
BUT whitelisting /lostpassword/ does not work…
I don’t know if you figured this out. But what worked for me was changing permalinks to something else, saving, and then changing back to “Name”. This fixed it for me.
