I am thinking of changing my .org site to the Sparkling theme but need advice on the ability to have a members only section that requires a username/password. Is there any information available about that?
Well, no , I don’t have such information, in shapely in on the front page section there is no such thing to prevent users by filtering them by user role, probably this will require some customization
You could password protect a WordPress page. Only members who have the password would be able to access the page.
Yes, that’s good solution but If I’m not wrong question is about particular section
