 * Hello [@patrickhaond](https://wordpress.org/support/users/patrickhaond/),
 * Indeed there might be a bug, but I think the bug is due to another parameter,`
   centered_on_this` or `this_post`that should not be used on a shortcode placed
   outside of a post/page. 
   I assume you want to set a shortcode in your search 
   result page (or category page), try to remove unnecessary parameters in your 
   shortcode and that should work 🙂
 * Tell me if my assumptions were right and if it’s working.

 * Thank you [@socrapop](https://wordpress.org/support/users/socrapop/) for your
   answer.
 * Actually the only other parameter I used was “this_post=true”, I deleted it and
   the warning message vanished.
