Help configuring a localhost server

Hi. I will need a little help on this. This is the first time I install a web server on any machine. My machine is a Celeron 700 mhz. The server is only for tests as an advice gived to me. I installed Apache 1.3.27, and php 4.3.ORC2, and everything runs under Win98SE. I haven't installed the MySQL yet. The problem follows. Every time I have tried to run a php script on the server (in this case http://localhost/prueba.php) the server gives an Internal Server Error and the error log contains this: [Tue Apr 22 17:52:33 2003] [error] [client 127.0.0.1] Premature end of script headers: c:/archivos de programa/apache group/apache/php/php.exe What can be wrong? I followed all the instructions of the instalation guide on the manual, a guide I founded at the internet, and a text file on the php directory. I've aready searched in my archive of old messages from this forum since April 2th of this year and no result of what could be happening. It might be some simple thing that I forget or mispell, but I have no much ideas of what could be happening. I'm searching for: - Ideas - Tutorials - Troubleshoting - People that could help - Other lists - FAQ's - ... Thanks in advance for any help provided. Everything is welcome.
