HTML character entities can cause RSS/syndication readers to fail when trying to read WordPress comment RSS feeds. This was a problem I was unaware of until reading of it on MacManX’s most recent blogroll dive and on Bryan’s post about this plugin
Fortunately, Kafkaesqui has written a plugin to resolve this issue.
I have installed and activated the plugin on this site so it shouldn’t be an issue here any more.
thank you for your work
