I have come across something that I can't figure out. When I add a form to a page, I am not able to change or add an email address to the section "Notify me by email when people submit this form". The original admin email is available, but nothing else. I tried to change this is the user settings, but the old email still shows up.

I had added to the "site.php" file:

obviously substituting the correct email address, but that didn't do anything. I'm stumped!

Image of what I am talking about is attached.

Any help on this would be appreciated. If I can manually edit it that would be fine.
