the url is http://rss.cnn.com/rss/cnn_topstories.rss It doesn't seem to work for the last tow or three days. Nothing new. Mac OS 10.13.3 Safari 11.0.3. None of the "fix a misbehaving site" options correct the problem. Which device I am using (iPhone, iPad or Macbook) doesn't seem to make a difference. This same problem happened a few years ago. I can't recall how it got fixed. Any help if it is on your end would be appreciated.
