Apache/PHP Configuration Problem on NT5

I have set up an ErrorDocument 404 in httpd.conf to point to a PHP file in the root of my documents. It was working, now suddenly it has stopped working. Here's the scenario: When I attempt to view a page that is not there, I receive a 500 Internal Error Message, as follows: ============================================ Internal Server Error The server encountered an internal error or misconfiguration and was unable to complete your request. Please contact the server administrator, rswfire@hotmail.com and inform them of the time the error occurred, and anything you might have done that may have caused the error. More information about this error may be available in the server error log. Apache/1.3.14 Server at swifte.dev Port 8080 ============================================ If I look at the error log, I find the following line: [Sun Jan 28 15:18:35 2001] [error] [client 127.0.0.1] Premature end of script headers: c:/program files/php/php.exe ============================================ Any ideas on how to fix this problem? _________________________________________________________________ Get your FREE download of MSN Explorer at http://explorer.msn.com
