Author Box

Hello,

I would like to use this plug-in to add an author box to my blog posts: https://wordpress.org/plugins/simple-author-box/

When I use it on the default setting, it adds the box to both my posts and my portfolio items, but I just want it on my posts. The plug-in support says that “If you want to manually insert the Simple Author Box in your template file (single post view), you can use the following code snippet:”

<?php if ( function_exists( 'wpsabox_author_box' ) ) echo wpsabox_author_box(); ?>

The problem is that I have no idea where to put to this snippet to make show up on single-entry blog posts only. Do you have any ideas? I am running an Enfold child theme with my own functions.php file.
