Code:

def activate(request, uidb64, token):

        user = CustomUser.objects.get(pk=uid)

        user.save()
        login(request, user)
        return redirect('account_activation_complete')
    else:

Hi Jeff, it's unclear that Django is at fault here. It looks like the uidb64 value isn't correct for what this code is trying to do. See TicketClosingReasons/UseSupportChannels if you need help debugging your issue, and reopen the ticket if you can explain why Django is at fault. Thanks!
