    As the title states I am getting the error:
    Permission on “/usr/bin/crontab” are wrong (4755). Please set to 4755.

    This only shows us when using the x3 theme on my cpanel. When I use the paper lantern I get the following error when I try to set an email or create a cronjob:

    Insecure dependency in require while running setuid.
    BEGIN failed--compilation aborted.

    This issue is very weird since the 4755 is obviously already set per the first error message.

    Any help would be awesome.

    Hello :)

    Do you notice any additional error messages in /usr/local/cpanel/logs/error_log when this occurs?

    Thank you.

    The only errors in that log are similar to this:

    warn [Cron::set_email] Encountered error in Cron::set_email: Insecure dependency in require while running setuid.
    BEGIN failed--compilation aborted.

    warn [Cron::add_line] Encountered error in Cron::add_line: Insecure dependency in require while running setuid.
    BEGIN failed--compilation aborted.

    info [cpanel] Permissions check for /usr/bin/crontab failed. Not executable. Unable to use user cronjobs via cPanel.
    Insecure dependency in require while running setuid.
    BEGIN failed--comilation aborted.

    It's possible this is related to an internal case opened for cron jobs on certain versions of cPanel and certain operating systems. Please post the output from:

    Code:
    cat /usr/local/cpanel/version
cat /etc/redhat-release
    Thank you.

    Internal case CPANEL-376 is open to address an issue where crontab on CentOS 7 will not work if a user renamed /usr/bin/crontab.relink.# (ex: /usr/bin/crontab.relink.1437150286) to something such as /usr/bin/crontab.relink.disabled. Could you post the output from the following command to see if that's the case on this system:

    Code:
    ls -al /usr/bin|grep crontab
    Thank you.

    To clarify, could you check the permissions of the /usr/local/cpanel/bin/jail_safe_crontab file? EX:

    Code:
    stat /usr/local/cpanel/bin/jail_safe_crontab
    Thank you.

    Could you open a support ticket using the link in my signature so we can take a closer look? You can post the ticket number here so we can update this thread with the outcome.

    Thank you.

    Lou, glad I was able to help, the issue just so everyone is aware was that "/
    usr/local/cpanel/bin/jail_safe_crontab" was set to 4755 when it should be set to 755 it does not need nor allow the setuid bit.
