I received email (10 by day) about an error cron task and I don't know how to fix it:
A cron task was failed, http://lovelybibi.fr/index.php?option=com_komento&
;task=cron crashed when we tried to run it. Error (php_network_getaddresses: getaddrinfo failed: Name or service not known) - (0)
Thanks for your help.
