WordPress 500 – Internal server error (edit)

I’m receiving “500 – Internal server error.” on the domain of my WordPress site.

Installed WordPress locally through Web Platform Installer in IIS (Win7).

Developed a landing page in Firefox locally, then FTP’d the site to the web server (which also hosts multiple sites from various domains).

Used MySQL Workbench 5.2 CE to create and export the database, which was also uploaded onto the server. Database was tested.

I’ve read all the posts relating to “WordPress” and “500 – Internal server error.”, none have helped.

I’ve tried creating the .htaccess file with the following contained:

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

# END WordPress

All file paths in IIS are correct.

Below is the wp-config.php file

<?php
/**

  * Secret Keys, WordPress Language, and ABSPATH. You can find more information

Please help!
