Hi.
I tried by several ways using crontab but nothing works:

1 php http://www.montear.c[...]e&task=cron
2 lynx -source "http://www.montear.c[...]task=cron" > /dev/null
3 php -q -d safe_mode=Off /var/www/vhosts/montear.com/index.php?option=com_parainvite&task=cron
4 php -q -d safe_mode=Off httpdocs/index.php?option=com_parainvite&task=cron
5 wget -0 /dev/null "/var/www/vhosts/montear.com/httpdocs/index.php?option=com_parainvite&task=cron" > /dev/null
6 wget montear.com/httpdocs/index.php?option=com_parainvite&task=cron
