Well i trust you because you are the only one along with Lele that are helpimg me here:

i tried what you said:

root at nikos [/home/nikos/public_html/cgi-bin]# service httpd restart
root at nikos [/home/nikos/public_html/cgi-bin]# python3 metrites.py 
root at nikos [/home/nikos/public_html]# cd foo-py/
root at nikos [/home/nikos/public_html/foo-py]# ls
./  ../  foo.py*
root at nikos [/home/nikos/public_html/foo-py]# ./foo.py 
root at nikos [/home/nikos/public_html/foo-py]# cd ..
root at nikos [/home/nikos/public_html]# cat cgi.err.out 
root at nikos [/home/nikos/public_html/cgi-bin]# cat /var/log/httpd/error_log 
root at nikos [/home/nikos/public_html/cgi-bin]# 

and i have run the script form browser but i still see nothing.

I insist that you will make the most of this if you access the VPS yourself.
it runs CentOS 6.4

Please accept, i trust you.
