Hey,
Looks like there might be an issue with the Crontab, if the Scheduled Job isn’t running
If you go to Admin->Schedulers, how does the line appear at the bottom?
It’ll show something like:
“* * * * * cd /var/www; php -f cron.php > /dev/null 2>&1”
If this differs from what appears in the Hostgator panel, it might be worth adding the line into Hostgator as a Cron job
Otherwise, I found a previous Forum thread in which users discussed Hostgator Cron issues, perhaps something here may be of help?:
