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