root at macgyver [/home/nikos/public_html/cgi-bin]# ls ../cgi.err.out 
../cgi.err.out
root at macgyver [/home/nikos/public_html/cgi-bin]# cat ../cgi.err.out 
root at macgyver [/home/nikos/public_html/cgi-bin]# 

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 at macgyver [/home/nikos/public_html/cgi-bin]# cat /var/log/httpd/error_log
cat: /var/log/httpd/error_log: No such file or directory
root at macgyver [/home/nikos/public_html/cgi-bin]# 

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.
