Internal Server Error FOR Perl script

[radofeya]

I don't know why my Perl script will return an 500 Internal Server Error for me.

This is the header of my Perl script which is the path to PERL
#!/usr/bin/perl -w
is that correct?

In addition, I have assigned 755 permissions to my cgi-bin folder.

Any else I should do before to use the Perl script?
