@schnarfed Can’t figure out what is populating h-entry: value. Don’t have mf2 installed. Using 2012 theme.
@jasongreen looks like mf1 backward compatibility. WordPress includes mf1 classes like hentry by default, which mf2 parsers also support.
@schnarfed If it’s in the WP core that will make it hard to find and edit the h-entry formatting.
