After upgrading to Dakar my webs no longer work with RSS readers like RSSOwl and Sage (plugin to Firefox).
RSSOwl says: The file is not a valid XML File. Error on line 177: The prefix "rdf" for attribute "rdf:about" associated with an element type "channel" is not bound.
And line 177 when I view source from WebRSS
I do not know RSS formats so I cannot say what is wrong. But my users are quite annoyed at the moment.
It seems the issue is that since Cairo it is now a requirement that the WebRss topic now contains a Set SKIN = rss. I guess in Cairo I had to put the ?skin=rss in the URL.
Maybe this change still deserves a mention in the upgrade docs.
This has survived itself now and that I am the only one that ran into this.
