Pre-process & post-process in 2.3

Where is pre-process and post-process scripts in 2.3 ?

What do you mean? It’s still under Admin>Scripts.

you right, for some reason it wasn’t showing, I had to logout and login back and now its showing.

It seems like the default DF instance Admin token has a short “time to live”. Maybe one hour? If it expires it only requests a new one if you change pages or do something out of the ordinary. This sometimes makes wierd things happen…
