There are two most probable causes.

1. if you upload your script using FTP, you must use ASCII as opposed to binary mode.

2. Windows as a hangover from its DOS days ends text lines with a carriage returns / newline pair where as Linux (based on Unix) ends text with just a newline character.

Compatability problems usually arise then when you edit your Perl/CGI script in notepad and upload to our Unix based servers.

We would therefore recommend a replacement for Notepad called TextPad. This will convert your (DOS formatted script) to one correctly formatted to Unix.
