I just installed WordPress 2.5.1 and ran wp-install.php. It asked me to log in. When I did so, I got a totally blank page in both Internet Explorer and Firefox. Firefox says "Done", so apparently the login was successful. When I tried to View Source, there was none - I got a blank page. However, using Dreamweaver, the files do seem to be up on the Web site properly.
I'm using SQL 5.0.45-community-nt and PHP 5.2.5. I looked in the database and everything appears proper - blog title, my administrator account, and so on.
Trying to go to http://www.theschoolforheroes.com/wordpress/wp-login.php takes me to http://www.theschoolforheroes.com/wordpress/wp-admin/ and gives the error HTTP 403 Forbidden, "The Website declined to show this web page."
