Could not lock Apache configuration

I can't add a new domain or subdomain in my host with Cpanel and that error is:

Code:

exit level [die] [pid=8465] (Could not lock Apache configuration: Cpanel::Exception::IO::ChmodError/(XID bww8ch) The system failed to set the permissions on one or more immutable (+i) filesystem nodes to “0600” (as EUID: 0, EGID: 0) because of the following error: Operation not permitted at /usr/local/cpanel/Cpanel/Exception/CORE.pm line 330, <$socket> line 1.

And also I was problem in chmod command then I fixed it (with reinstalled coreutiles )
but I have this problem in cpanel again.

Thanks for your answer.
If I rebuild it, I will lose my any info or configs?

 

Thank you
So how I can do this job?
And if I do it then Will cpanel response?
