Unable to toggle visibility in Customize menu

Hi. I am using indico 3.3.4. When I enable “customize menu”, I am unable to view customized menu like “Scientific Program, Contribution list, etc.” on main page. Help in this regards please.

Did you also ensure the content for those pages exists? e.g. the contribution list becomes visible once there are accepted contributions and the list is enable on the contribution configuration as well.

I think that was the exact reason. Thanks for guiding.
