Suddenly 'contact list' cannot see a private blog
 

One of my members sent me a message today that her blog is suddenly blocked from everyone, including people on her contact list. Before today, it could be seen. Today, no one can see it.

I haven't changed anything in the admin panel in weeks, except to disable the old journal system, vbjournal-- vBlogs wouldn't be looking for anything from that system, would it? She hasn't changed anything in her back end in a while. I checked her settings and they're all correct.
