ISPConfig documentation states that @reboot can be used in the months field of the cron jobs tab. However, no matter how I input it, I keep getting a 'Invalid format for months.' error. How do I properly use @reboot in the cron jobs of my users?
This problem might be caused by a change of the regular expression we use. Can you post this in the ISPConfig bugtracker? http://bugtracker.ispconfig.org/
