The wp database and account have been created and given full permissions to the database. The account information has been entered in the wp-config file. MySql is running as a service and I can connect to the database as the wordpress user from the command prompt.
I've installed php according to the wordpress instructions and php_info() displays the proper results in my browser. c:\php is in my path. I've configured php as described in the WP instructions. The .dll's for mysql and mysqli have been un-commented in the php.ini file.
Wordpress 3.0.1 has been downloaded, unzipped and placed in the root of my IIS document directory. wp-config has been edited as described in the WP directions.
The web server has been created with a path to c:\inetpub\wwwroot\wordpress. php has been added as a web service extension. The dlls are all on the default path.
Problem: http://localhost/wp-admin/install.php returns
HTTP 500 Internal Server Error.
I have to have missed something or have something mis-configured, but I've followed the directions to the letter and still get this error.
Any suggestions would be greatly appreciated. Ready to move to Concrete5 or other product.
