 * I’ve switched to PHP8 on live recently. Lately noticed `debug.log` has started
   steadily filling with these:
 *     ```
       PHP Warning:  Undefined array key 109 in /plugins/pareto-security/pareto_functions.php on line 2092
       PHP Warning:  Undefined array key 110 in /plugins/pareto-security/pareto_functions.php on line 2095
       PHP Warning:  Undefined array key 110 in /plugins/pareto-security/pareto_functions.php on line 2096
       ```
