Hello – I am having the same problem after upgrading to the latest Enfold theme Version: 4.6.3.1. The “Advanced Layout Editor” button no longer shows up when I create a new Event using The Events Calendar Plugin. It was working before, and I need all the templates in the Advanced Editor within The Events Calendar. Can you please advise ? The “Advanced Layout Editor” button is still working properly when I create a new page, and my templates are there, etc.
