Well this burned several hours of my time to get cronjobs running on a new server. I was manually setting crontab permissions to 4755 as CPanel requested before inputing a cronjob – but the permissions kept resetting themselves so my cronjob wouldn’t save. Do it from your ssh console as root instead; here is the fix:
If you are receiving the error “/usr/bin/crontab permissions are wrong. Please set to 4755″ when in the cron section of cPanel, the commands below may correct the error for Redhat/CentOS/Fedora servers.
Log into the server via ssh or the console as root and run:
chmod 4755 /usr/bin/crontab
