Where does the division by zero happen? I just get "You need at least 'view' access to idSite = 1" (which I have, and I am logged in).
There is a typo in the URL.
idSite is provided twice.
I do not recall how this URL was given to me.
Removing idSite triggers a different error.
To reproduce the division by zero issue, keep the same URL but provide the auth token.
Appears fixed in 2.0!
