Yes, this hasn't worked. For some reason, the email is working, but I'm getting server error logs. Also, as an effect of that, I'm also having issues with the password reset links. The email is sending just the link is giving a faulty link, which just leads to error on the forum website when you click on that link.
The link you've given reflects a board URL other than the one you have entered. It reflects a Board URL with "/index.php" applied (note the description of the option). I would guess you changed this since the email was sent?
