I am trying to install WordPress to a web hosting site. I've followed the steps outlined here: http://codex.wordpress.org/Installing_WordPress. Downloaded the zip file, extracted it, created the sql database in the web hosting control panel, making note of the database name, user name and password. Uploaded the contents of the wordpress directory to the root of the site. Began step 3 by using the "preview site" link on my web hosting control panel, because the domain name of the proposed site has not yet been pointed to these servers. Got the screen that asked for the database details. Entered them, using "localhost" as the database host. Got White screen after clicking submit.
Thought perhaps localhost was not the correct name for the database host, so contacted my hosting company - they confirmed that localhost is correct. So then I went to the wp-config-sample.php file in the unzipped folder on my computer, opened it, renamed it wp-config.php, changed the values for the database manually, then uploaded it to the root of the site. But now, when I point my browser to http://MySite/wp-admin/install.php I get the white screen.
I'm using the "preview" url accessible in my web hosting control panel, which consists of the domain name which will eventually be used if I can get this thing up and running and the client likes it (but which is not currently pointed to the host's servers, since they already have an existing site hosted elsewhere) followed by the ip address, followed by the hosting company's name followed by .com - so it reads http://domain-name.00.00.00.000.hostingcompanyname.com/wp-admin/install.php.
I've never worked with WordPress before, so I'm a bit out of my depth here. Need help, can't go any further with the white screen of death!
