friendlyway composer 7

Adding a valid RSS feed URL I'm getting the following error message: "The specified URL could not be retrieved!". composer doesn't support all RSS formats. Possible RSS formats are 0.91, 0.92 and 2.0, Atom feeds are not supported at all. Please ensure that your RSS feed is in one of the listed formats. If not, you can try to check your RSS source  for RSS feed in the proper format since many RSS sources (for example a  newspaper homepages) provide RSS feeds in different formats.
