I have looked through the Forums already and found no real answers to this issue. I am running an internal multisite WP instance and am password protecting posts. Chrome, Safari, Firefox, and Opera all allow access with no problem. However, when in IE (7,8, & 9), when the (correct) password is entered in the WP prompt, the page simply reloads, with no change. I have gotten this to work when I allow 3rd party cookies (which makes no sense to me). I've also got it to intermittently work in 7 & 8 without that change. Nothing is making sense at this point. Any thoughts?
