Thank you Denzel
Many of the options are now showing with padlock indicating I need to upgrade to Evolve+ Premium which I have already paid for.
In particular I tried to set up Front Page Content Boxes which do not appear and many other options are padlocked too.
Also is there more detailed info on using the customisation options please? In particular I’m now trying to find what html to use in the Learn More Slide Buttons on the Bootstrap Slider.
