XFileSharing Pro - Error when changing - XfileSharing Pro

[ramin]

Hi
I have a problem in version Xfilesharing Pro
The website admin panel when I want to save the settings I error
"Can't write XFileConfig"
Shows

Chmod files:
cgi-bin/XFileConfig.pm 666
cgi-bin/XFSConfig.pm 666


The problem is the access?
The problem is my Perl version?

Profile server:
Centos 6.4
Apache
Mysql 5.5
perl v5.10.1
perl LWP module

Please guide
