root@macgyver [/home/nikos/public_html/cgi-bin]# ls ../cgi.err.out=20
../cgi.err.out
root@macgyver [/home/nikos/public_html/cgi-bin]# cat ../cgi.err.out=20
root@macgyver [/home/nikos/public_html/cgi-bin]#=20

Also i have foudn the error log and i tried to view it but it was empty and=
 then i removed it and then run the script both from shell and broswer but =
it didnt reappeared.

root@macgyver [/home/nikos/public_html/cgi-bin]# cat /var/log/httpd/error_l=
og
cat: /var/log/httpd/error_log: No such file or directory
root@macgyver [/home/nikos/public_html/cgi-bin]#=20

Maybe its somehtign wron with my enviroment?
Should we check the Apache and CGI enviroment somehow and also make sure as=
 you say that *I* run the CGI scripts and not user 'Apache' ?

Tell me what commands i should issues please and i will display the output =
to you.

Thank you Cameron, for helpimg me. Somehow the script doesnt seem to be the=
 issue in  my VPS.
