What is the Legacy Administrative Interface? How do I access it in version 9.x and newer?
The Legacy Administrative Interface is real-time web client and interpreter between the Graphical Administrative Interface and the PostgreSQL database. It is based on HTML and Flash converting database queries and information into a graphical representation of the output using Web based browsers.
From the HTML 5 new interface, on the top right side of the screen, click on the two gears icon, then OPEN LEGACY INTERFACE.
