I need your help please
Inin a production system i found crontab entries was removed because i typed crontab -l with username corasc and didn't show anything.
i asked the administrador to restored the mentioned crontab, he restored the crontab:
The problem is when restored the crontab file is not executing any entry:
What happenned:?
i checked up the /usr/lib/cron/cron.allow and the username corasc is included, also checkup the /usr/lib/cron/cron.deny and it doesn exist

i checked up the crontab file and permissions and:
ls -lrt /var/spool/cron/crontabs/corasc
-r-------- 1 root colombia 1072 Dec 4 02:50/var/spool/cron/crontabs/corasc
BEFORE BEING REMOVED THE CRONTAB, IT WAS WORKING, si i show you the crontab lines
corasc@altamira00 : corasc > crontab -l
