Hello I have read that adsense integration is not an available option for free version any more. However, you suggest that we can use the custom code to make ads play.
I have tried both to add the code to the custom code block and to hardcode the "single.php" file by adding Adsense script code right after
<?php get_template_part( 'related-posts' ); ?>
No Ads are displayed with any of the mentioned midifications.
On the other hand I have added the AddThis social sharing code for smart layers either to the custom code block or to the "footer-top.php" file and the module is working properly.
Are you blocking/filtering the adsense code on the free version?
