I'd appreciated your answer .

 

Thank you
This issue has fixed by an employee of cpanel.
He Said
" The mail folder permissions were also set wrong, but I was able to correct all those at once using /scripts/mailperm. However, there is no fix for the .cpanel directories in the user's folders. The .cpanel directory and the .cpanel/caches directory must be chmod 700 and must be manually changed.
I'm not sure how this happened, as cPanel nor its scripts would make these type of permission changes. You or your systems administrator will need to visit each home directory and make sure that the .cpanel and .cpanel/caches are chmod 700. Do not do them recursively, just on each folder:

# cd /home/<user>
# chmod 700 .cpanel
# chmod 700 ./cpanel/caches "

Then I run these codes to fix permission for each directory .

for dir in /home/*
do
if [ -d "$dir" ]
then
username=$(basename "$dir")
cd $username
chmod 700 .cpanel
chmod 700 .cpanel/caches/
cd ..

fi
