Coauthors Plus and multiple WP Bio boxes

Hi,

We are using the Co-Authors Plus plugin and trying to display multiple WP Bio boxes on articles with multiple authors.

We’ve read this thread and tried the code you left there: https://www.ads-software.com/support/topic/plugin-wp-biographia-multiple-author-boxes-are-showing-up?replies=9#post-3692157

Our issue is that wpb_the_biography_box() doesn’t output anything for us, even in a very simple form:

wpb_the_biography_box( 'configured', '16' );

This code is on single.php. We use get_coauthors and can successfully display an array of the authors, but can’t show their bio boxes.

We are on WP 3.9.1 and Genesis 2.0.2, using a modified Genesis Sample Child Theme. WP Biographia 3.3.2 and Co-Authors Plus 3.1.1. Bio boxes are working fine in all other respects. Any advise is appreciated, thanks.
