What do you mean? What have you tried?
1. Start ctrlr
2. From dropdown menu go to: Panel -> LUA console
3. Click on the bottom part of the Console
4. type console("Hello world")
5. The text “Hello world” should appear on the upper part of the Console.
If this works, you can try using console(“Any text bla bla”) in LUA code you use for your Panels.
I have reverted to Ctrlr 5.4.29 after having too much trouble with 5.5.2.
