Message
Feeds should not be served with the 'type/subtype' media type
Explanation
The web server is reporting an unexpected MIME type for a feed. Although we tried to parse it as a feed, aggregators may well report this as an error and act as if the user had pointed them at something other than a feed.
RSS feeds should be served as application/rss+xml
(RSS 1.0 is an RDF format, so it may be served as
application/rdf+xml instead).
Atom feeds should use application/atom+xml.
Alternatively, for compatibility with widely-deployed web browsers, any of
these feeds can use one of the more
general XML types - preferably application/xml.
Solution
Use the appropriate MIME type for your feed.
- For static content served with Apache, use the AddType directive.
- For static content served with Microsoft IIS, add a MIME type.
- Other information can be found here or in the documentation provided by your server.
