I set up this code ages ago so I could upload news to my website, I just changed hosting plans and uploaded all the same files.. but my admin section is now all messed up. I presume some of the code was too ald for my new server

Can anyone please help.. it would be much appreciated...

I get

        $line .= "|" . $HTTP_POST_VARS['news'];
        $line = str_replace("\r\n","<BR>",$line);
        $line .= "\r\n";
