 * Would anyone please know what is causing this message in the debug file of my
   wordpress installation:
 * PHP Deprecated: trim(): Passing null to parameter #1 ($string) of type string
   is deprecated in /www/doc/www.mydomain.com/www/wp-content/plugins/better-wp-security/
   core/core.php on line 1102
 * Line 1102 of the core.php file then is
 * $home_path = trim( $home_path, ‘/’ );
 * The PHP Deprecated line keeps being added every few seconds, I have thousands
   of them in the debug file.
 * I am running PHP 8.1.18. All my plugings and WP core are the latest and up to
   date.
 * Thanks
