	I do not see anything wrong with my script, but when I run it I get a 500 Internal Server error. Why is this?

Solution The problem you are getting is the result of many possible errors in your script, but the best advice that can be given is to generate the error, then look in your logs directory. When in your logs directory, view your error_log file to see what error has occurred. This can usually help a lot.

Something that many users are not aware of (and this is especially important when making Perl scripts), is that Microsoft systems don't write text in the same way as Unix systems do. When you save a document in Microsoft text format (ie in Notepad), every line ends with CR/LF (which means Carriage Return - go to the start of the line, and then Line Feed - which goes down one line). Unix simply needs a CR, not CR/LF. LF is represented in Unix as the character ^M (as LF is a non-printable character).

Looking at perl files in a Unix editor such as vim indicates ^M's if they exist. To make sure that your scripts don't fall to the wrath of the ^M's, which breaks them, try running a DOS2UNIX program on them which strips the ^M's before an upload.
