well if you want to run it as the user and you have shell access then execute this from the commandline:
Which will pull up the crontab editor for this cPanel user you have defined. Meaning "cpuser" is your cpanel username for the site that you want the cron setup for.
Then add something like this:
Code:
MAILTO=you@yourdomain.com
0 4 * * * php /home/cpuser/cron.php
The above assumes you have cron.php setup in the site root where the below could likely be used if the cron.php is in the web root, assuming that executing cron.php in a browser works...
Code:
MAILTO=you@yourdomain.com
0 4 * * * GET http://yourdomain.com/cron.php
Both of the above fire off the script at 4 AM server time and email the results to the address you specify in the "MAILTO" line.
