O'Reilly Website Problem

I am running PHP 4.03 on O'Reilly website 2.5 I have specified the content and associations as directed in O'Reilly's online support (what little of it exists anyway). I am running into an issue where all requests to any PHP page causes a termination of PHP.exe on the server. I have seen a couple of other articles where people have had the same problem, but no solution. Does anyone have any idea what the problem could be or where I can find more info related to this issue? I have tried: - Switching versions of PHP to everything from 3.0 - 4.37 - Specifying the "doc_root" in php.ini - Removing and re-installing PHP - Troubleshooting content associations in O'Reilly WebSite Pro Thanks Jeff
