For some feeds the <link> tag is ignored, just <guid> is found. Mail Header shows: X-RSSyl-URL: <empty> Message-ID: $GID-URL Maybe the most prominent Feed where this occurs: https://netzpolitik.org/feed/ Other Feed: http://c3d2.de/pentacast.xml The pentacast feed is aggregated in the following "harvester", the feed of this harvester, which includes the pentacast feed, is fine again: http://astroblog.spaceboyz.net/harvester/rss.rdf Both problematic feeds have an empty "atom link" tag. Thanks for fixing! koeart
