We have a preexisting site created with PHP-Nuke. We want to change to WordPress. I've installed WP in the root directory of the site where the preexisting sites homepage is located. When I navigate to the home directory http://blackhawkhoa.net or when I click the site URL in the admin control panel I'm taken to the preexisting site homepage. Also, when I click view on any another page that I created in WP I get an 500 Internal Server Error.
The only thing I need from the preexisting site is the static content (pics, docs etc). I want to be able to see the Home page I created in WP and the other pages. How do I configure this?
