How to switch off (Read Only) on 'New Interface' ?

Hey there,

I’m busy following this tutorial off Youtube and have run into a hiccup, at 4:17 he is able to edit the Interface but mine is read only and have no idea how to change that, I’ve tried restarting, running the engine in administrator mode and neither worked, any suggestions of how I could fix this?

Thanks in advance.

Hello Accept333.
His is also read-only but the interface is just been updated with the newer versions. The way to edit the interface is to set the inputs and outputs.

Ahh! Feel stupid, thanks mate!
