I get this error on the feed validator:
is feed is valid, but interoperability with the widest range of feed readers could be improved by implementing the following recommendations.
line 47, column 0: content:encoded should not contain iframe tag (3 occurrences)
Here is the code that is highlighted:
<content:encoded><![CDATA[<p><iframe width="520" height="390" src="http://www.youtube.com/embed/_gsRHEHAY6Y?feature=oembed" frameborder="0" allowfullscreen></iframe></p>
Can someone please help to correct?
