Symptoms
The Automic Script editor can´t open Includes from Client 0.
Cause
Due to security rescrictions which prevent users to interfere with objects in client 0.
Resolution
There is no possibility to view content from Includes client 0 in your current client.
As a workaround you can establish a connection from every Dialog Client to Client 0 and view the Inculde there. We would recommend to create a user with read only rights on these objects to avoid unwanted changes in your system client from usere.
