I tumble to do!
It’s necessary add code in file single.php Edin theme
<?php get_template_part( 'content', 'hero' ); ?>
In file extras.php Goran theme add is_single() in line 18.
I copy file single.php to Goran theme and only Edin theme update.
Thanks for the explanation. I will continue to study WordPress.
Ok. I am ready to give up the update and want to understand how it works.
Why not combine the themes Edin and Goran?
