I have tried everything, chmod the files, reinstall perl modules, rechecking the configuration etc!!!! Can not figure out what is wrong!!! but I can guarantee that the script is not broken!

Answer 1

Try running:

perl -c /var/www/cgi-bin/upload.cgi

Quote from perldoc perlrun:

   -c   causes Perl to check the syntax of the program and then exit
        without executing it.  Actually, it will execute "BEGIN",
        "UNITCHECK", "CHECK", and "use" blocks, because these are
        considered as occurring outside the execution of your program.
        "INIT" and "END" blocks, however, will be skipped.

Answer 2

Run your script with perl -w /var/www/cgi-bin/upload.cgi.

I should write out an HTTP header

Content Type: text/html
[blank line]

If not, your script not working well. Maybe the other server pass you a variable and your script won't create a proper header any more.

Paste this code in the very to of your script. If your script looks bad, but working, you found out the bug.print("Content Type: text/html\n\n");

print("Content Type: text/html\n\n");
