Hi, first of all, sorry for taking so long to respond. I have had covid and I have been in bed for many days, so I didn’t validate your post until today.
Responding to your question, “Core disabled” means you don’t have started the bot. Once you access to the GUI, click on “Start Trading” button, then the core will be enabled and the bot will start trading. Remember to have at least one pair added before clicking on “Start Trading” button.
