Checking the Cron Job logs requires root access. If you have** root access** you can run the following command (replace “scriptname.php” with the name of your script):
grep "scriptname.php" /var/log/cron
If you have shared hosting, no root access, or do not wish to use the command line, you should specify a cron job email. Because this could quickly flood your inbox, you may want to set up a specific email address for this purpose.
