 * I have discovered an issue. When I do a search for “timeline” I get this error:
 * Warning: call_user_func_array() expects parameter 1 to be a valid callback, second
   array member is not a valid method in /XXX/wp-includes/class-wp-hook.php on line
   286
 * I can not reproduce the error with any other word so far. Any help is greatly
   appreciated.

 * This error also shows up if I search for “page” which is a post type and “timeline”
   is also a post type

 * That error is not a Relevanssi error, so I can’t really tell what’s happening
   there. Could you please install [Query Monitor](https://wordpress.org/plugins/query-monitor/),
   that would show more information about the error message and how it relates to
   Relevanssi.

 * oddly enough the issue went away. maybe it was a caching issue on my side. thank
   you for responding quickly.
