An enormous amount of failing sites for three to 4 days now!
This has been happening with my web rings as well as my own sites over the past three to 4 days. This has occupied several hours each of these days. I fear checking tomorrow as this enormous failing of sites may continue.
I hope your theory about Admin attempting to get managers to manage better isn't true. I manage my rings very strictly already so there isn't anymore I can do.
Admin, please tell us why the nav code checker is behaving this way?
