Post content missing, Genesis

Hello,
I have no idea what I did, but my post content isn’t showing on my featured post, or on any post when I visit the post page.
I have changed themes, and it is a theme problem. It seems to be in my functions file, but I can’t figure out where. I recently added:

/** Previous and Next Links **/
add_action(‘genesis_after_comment_form’, ‘custom_post_nav’);
function custom_post_nav(){?>
<div style=”font-size:13px; padding:2px;”>
<?php previous_post_link(‘<b>Previous Post:</b> %link’) ?>
<?php next_post_link(‘<b>Next Post:</b> %link’) ?>
</div>
<?php }

And not seeing posts happened sometime after that, although I’m not sure when. When I remove that part of the code, I am still not seeing my content. Hmmm. ??
Any help would be so appreciated! https://www.elainegriffindesigns.com/blog/
