Archive Intro

@microbe You can add this to your active theme’s functions.php so that shortcodes and oembeds will be processed:

add_action( 'genesis_meta', 'custom_filter_archive_intro_text' );
function custom_filter_archive_intro_text() {
	global $wp_embed;
	add_filter( 'genesis_term_intro_text_output', array( $wp_embed, 'autoembed' ) );
	add_filter( 'genesis_term_intro_text_output', 'do_shortcode' );
}

@microbe If this is for the /portfolio/ page itself (rather than one of the /portfolio-type/ pages), you can try this instead of the above code:

add_action( 'genesis_meta', 'custom_filter_archive_intro_text' );
function custom_filter_archive_intro_text() {
	global $wp_embed;
	add_filter( 'genesis_term_intro_text_output', array( $wp_embed, 'autoembed' ) );
	add_filter( 'genesis_term_intro_text_output', 'do_shortcode' );
	add_filter( 'genesis_cpt_archive_intro_text_output', array( $wp_embed, 'autoembed' ) );
	add_filter( 'genesis_cpt_archive_intro_text_output', 'do_shortcode' );
}
