I am about to launch a members only section to my site, and I'm finding that sub pages within the member area are not protected and are accessible via the URL. Is this correct? Did I do something wrong in the construction of the site? Attached is a screen cap of the structure. The site is currently password protected for testing purposes. If you navigate to the Image Sets page, you get a log in prompt, but only then. Thank you in advance!
