Server Alias Incorrect server wide.

    Fix :

/var/cpanel/userdata/users/domain.com

Correct Server Alias and then run

/scripts/rebuildhttpdconf

/usr/local/cpanel/bin/apache_conf_distiller --update.       Script to do the same.    cd /var/cpanel/userdata

find ./ -type f > ~/list1.txt

for i in `cat ~/list1.txt`; do x=`echo $i | cut -d/ -f 3`; if grep -q ^$x$ /etc/localdomains; then echo $i;fi;  done  > ~/list2.txt   

for i in `cat ~/list2.txt`; do domains=`echo $i | cut -d/ -f 3`; replace "serveralias: $domains" "serveralias: www.$domains" -- $i; done
