I have a Notice: PHP message: PHP Notice: SPX: spx_profiler_stop (): profiling is not enabled in index.php

// index.php
<?php
spx_profiler_start();
require 'kernel.php';
$router->resolve();
spx_profiler_stop()

Profiling is simply not enabled.
What is the PHP SAPI ? If it is a CLI script the command line prefix must be added on your own, the control panel only displays it for the sake of convenience.
