I'm seeing the home page but errors everywhere else

The Windows version of Apache treats files and folders slightly differently, and likely you will see errors on every page but your index page. To fix this, add the following line to your httpd.conf file:

AliasMatch ^/index/.* "C:/apache/htdocs/index"

Make sure you adjust the paths in this line according to the location of your site within the document root, and the location of your Apache installation.
