Replying to: Re: Need Someone to Look Under the Hood by Revival Fire
Post: Dennis,

I fixed that but it still does not work. I have one other cgi that I know works in my cgi-bin so I know that it must be functional. That script is at [url=]PhoneChristian Rates

Someone gave me another script that was supposed to work, look in Beginners forum, but it just will not! I even chmoded to 777. The only thing I can think is to try to redo the cgi script he gave me on my computer and redo the upload by ASCII just to make sure I did it right.

Here is the error message I get with the jumpbox cgi...

[Wed Nov 7 10:41:43 2001] [error] [client] Premature end of script headers: /home/pc/phonechristian-www/cgi-bin/jumpbox/

Here is the script...
