 I got a

 **Warning: Attempt to read property "comment_count" on null in [...]\wp-
 includes\general-template.php on line 3352**

 let's check if the object exists and the property is not empty.

 Original line:

 {{{if ( $show_post_comments_feed && ( comments_open() || pings_open() ||
 $post->comment_count > 0 ) ) {}}}

 possible patch, something like:

 {{{
 if ( $show_post_comments_feed
      && isset( $post )
      && $post instanceof WP_Post
      && ( comments_open() || pings_open() || $post->comment_count > 0 )
 ) {
 }}}
