I just started receiving this warning message from Feed Validator about my WP 1.52 Podcasting only blog, http://www.macreviewcast.com. The feed is http://www.macreviewcast.com/wp-rss2.php?category_name=podcasts
The warning message is: This feed is valid, but may cause problems for some users. We recommend fixing these problems.
line 52, column 12: Avoid <content:encoded> (10 occurrences)
I did not change my wp-rss2.php file at all and this was valid before. Although it's still valid, I heard from two listeners that told me they were having trouble with my feed... any ideas?
