Because OVH doesn't support URL for Cron, we need to create and add custom PHP file:

<?php
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,'http://www.lovelysecret.be/wp-cron.php?f8c7891ad19adc
0dde19beb11eb67b2b&action=wysi
ja_cron&process=all');
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch, CURLOPT_TIMEOUT, 10);
