I have a server with WHM / cPanel, and I have a problem with "Cron Jobs".
I configured cron to account, it still works.
The problem is that when I go into the account, it shows me
No Cron Jobs
When a cron job is added was this message
You (user) are not allowed to use this program (crontab) See crontab(1) for more information.
I had problems with servers running CentOS 7, not with CentOS 6.
Here is the solution for this pronlèmes:
This connect via SSH and run
rpm --setperms cronie
