This feed, http://mac360.com/feed/, had been working correctly since I joined Newsblur. Since July 2, 2015, however, it has stopped working. The feed validates https://validator.w3.org/feed/check.cgi?url=mac360.com and I am able to add it to my Firefox Live Bookmarks. In Newsblur, however, it now comes up as a misbehaving site, on my iphone app, in my browser, and in ReadKit. Any thoughts? Thanks.
