Force the primary menu to be displayed using the genesis_pre_get_option_
filter.
add_filter( 'genesis_pre_get_option_nav', 'child_get_option_nav' ); function child_get_option_nav( $opt ) { $opt = '1'; return $opt; }
Tip: Use this in conjunction with removing unused theme settings metaboxes so that users are not confused with why their settings are not being saved.
