Error 500: Premature end of script headers

Question

I get a \"Premature end of script headers: contactform.cgi\" error message when running the below script. What frustrates me is that I ran this as a .php on another server

Answer 1

Check your line endings! If you see an error about the file not being found, followed by this "premature of end headers" error in your Apache log - it may be that you have Windows line endings in your script in instead of Unix style. I ran into that problem / solution.
