 * I’m getting a message in query monitor. I’m not sure what this means and I’m 
   wondering if anyone can help:
   call_user_func_array() expects parameter 1 to be
   a valid callback, function ‘ws_private_posts_subscribers’ not found or invalid
   function name
 * Location: 
   wp-includes/class-wp-hook.php:308do_action(‘init’)wp-settings.php:
   617
 * Component:
   WordPress Core

 * The function name ws_private_posts_subscribers sounds more like an individual
   function. Do you have a child theme and a hook there that refers to this function?
   Also a plugin like Code Snippets could contain this.

 * Thank you! I found the function in my functions.php file and remedied it.
