Hi,

I checked documention of  Adning Advertising plugin. I don't see any requirement theme have hook or code to support then plugin.

the code content single of pennews theme :

<div class="penci-entry-content entry-content">
 <?php
 penci_render_google_adsense( 'penci_single_ad_before_content' );
 the_content( sprintf(
 wp_kses( __( 'Continue reading %s <span class="meta-nav">→</span>', 'pennews' ), array( 'span' => array( 'class' => array() ) ) ),
 the_title( '<span class="screen-reader-text">"', '"</span>', false )
 ) );
wp_link_pages( array( 'before' => '<div class="page-links">' . esc_html__( 'Pages:', 'pennews' ), 'after' => '</div>', ) );
 penci_render_google_adsense( 'penci_single_ad_after_content' );
 ?>
</div><!-- .entry-content -->

If you want use Adning Advertising plugin. Please contact with author of plugin and ask theme the theme must add any hook or custom code to support show "Auto Positioning" on content post.

You can send content single post of PenNews theme to author of  Adning Advertising plugin

Best Regards,
