password protection, media screen, and header images

Hi. Two problems and a question: 1. Our blog page has visibility set as password protected and the page is labelled that way in the dashboard, but the protection isn't working. I know we can password protect each individual post, but it would be easier to just have the page protection work. (https://wellnesswarriorsboston.org/trainingblog/) 2. I'm ready to go live with my new home page (https://wellnesswarriorsboston.org/featured5/) but #main and .sidebar-primary wrap horribly on a small screen. Solution? 3. Is there an optimal max number of randomized header images before compromising loading time? Alice
