You may get this error during Apache restart in cPanel.
Invalid command ‘BytesLog’, perhaps mis-spelled or defined by a module not included in the server configuration
In order to resolve the issue you have to recompile the module mod_log_bytes.
do:[root@HostDire ~]# cd /usr/local/cpanel/apache
[root@HostDire ~]# /usr/local/apache/bin/apxs -iac mod_log_bytes.c
[root@HostDire ~]# /etc/rc.d/init.d/httpd restart
Hope this helps!
