 * The plugin is causing this to be logged with PHP version 7.1, resulting in an
   ever growing log file:
 * [12-May-2019 07:27:45 UTC] PHP Warning: Parameter 2 to sbtonly_filter() expected
   to be a reference, value given in /wp-includes/class-wp-hook.php on line 286
 * Could you please check?
 * Many thanks

 * in the plugin file `search_by_title_only.php` replace: `function sbtonly_filter(
   $search, &$wp_query) {` with `function sbtonly_filter($search, $wp_query) {`.
 * `$wp_query` does not need to be passed by reference and WordPress does not allow
   this when using filters or actions.
 * The warning will go away 🙂

 * Hi, I’m still running into this error. Perhaps an update could be released to
   resolve this. Thanks!
