WordPress 404 Error

I开发者_JAVA技巧'm trying to update wordpress and i'm seeing these errors:

Apache Server at www.3cdesignsolutions.com Port 80

The requested URL /wp-admin/your_website_url_here/wp-admin/upgrade.php was not found on this server.

Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.

Anybody know what file I need to edit? Where can I enter in my website url?

You'll need to fix this mistake in the database directly, since you can't log in to the wp-admin to do it there. Find the row for the siteurl option in the wp_options table and fix its value.
