PHP3 was stopped a long time ago. Maybe its time to upgrade the scripts to PHP4 standards

Anyways the reason for this is the php3 extension. Find this line in your apache config file (httpd.conf):

AddType application/x-httpd-php .php

And below it place:

AddType application/x-httpd-php .php3

And replace this:

DirectoryIndex index.php index.html index.php.var index.html.var

With this:

DirectoryIndex index.php index.php3 index.html index.php.var index.html.var index.php3.var

This is untested but it should work
