Just upgraded to 2.3.1... I login (admin) and can write, configure, etc. but when I click View Site, I'm no longer logged in and see the blog as if I'm just hitting the URL as a new browser instance, therefor I don't see Private posts. If I click login, howver, I'm right back in admin mode without being prompted for username/password.
Before upgrading I would stay logged in (as admin) when I'd click View Site. I'm a WP novice and appreciate any and all help.
