I apologise if this has been asked before. I gave up after searching for 30 minutes, The document root for my site is: /var/www/clients/client1/web1 I'm using Boonex Dolphin/Cheetah and they recommend the following cron job: [email protected] * * * * * cd /var/www/my website.com/web/periodic; /usr/bin/php -q cron.php ISPConfig suggests the following example: /var/www/clients/clientX/webY/myscript.sh or http://www.mydomain.com/path/script.php How do I convert the Dolphin recommendation to the ISPConfig suggestion? Can I use: (1) /var/www/clients/client1/web1/periodic; /usr/bin/php -q cron.php or 2. http://www.mywebsite.com/periodic; /usr/bin/php -q cron.php Or do I have everything back to front? Finally, where do I enter [email protected] ? Is this correct? [email protected]; (plus 1 or 2 above?) I've tried all combinations, but I'm not getting any mail. Thanks in advance.
