                  <code>*/15 * * * * wget "<?php echo MyTool::getUrl().'?update&cron='.$kfccron; ?>" -O /tmp/kf.cron</code><br>

                  <code>0 * * * * wget "<?php echo MyTool::getUrl().'?update&cron='.$kfccron; ?>" -O /tmp/kf.cron</code><br>
                  If you can not use wget, you may try php command line:<br>
                  <code>0 * * * * php -f <?php echo $_SERVER["SCRIPT_FILENAME"].' update '.$kfccron; ?> > /tmp/kf.cron</code><br>
                  If previous solutions do not work, try to create an update.php file into data directory containing:<br>
                  <code>
                  &lt;?php<br>
                  $url = "<?php echo MyTool::getUrl().'?update&cron='.$kfccron; ?>";<br>

                  </code><br>
                  Then set up your cron with:<br>
                  <code>0 * * * * php -f <?php echo dirname($_SERVER["SCRIPT_FILENAME"]).'/data/update.php'; ?> > /tmp/kf.cron</code><br>
