I think my issue was that my bookmark was to www.ironcrown.com, but after logging in it was taking me to ironcrown.com. The cookies and login data maybe were not being shared between those two versions of the URL. So every time I went to www.ironcrown.com, I was not logged in, but following any links would go to ironcrown.com where I was logged in.
Moral of this story for users might be to delete your bookmark and create a new one. There is probably a way to fix it on the site side, but I don't know what that would be.
