Do you know how to make your site show up on Google?

Hi everyone,

I had a previous non-Wordpress site and was getting a lot of interaction with new customers through Google searches. Since I switched to Wordpress, my site isn't coming up. I found this site where you can find out if your blog is working, and this is the response I got. It apparently isn't showing up anywhere...any tips on what to do?

The important stuff:

Your web server [192.232.218.157] is working fine.
Your RSS feed returned a 404 error.
WP Super Cache error: The constant WPCACHEHOME must be set in the file wp-config.php and point at the WP Super Cache plugin directory.
Your robots.txt file appears to be invalid:
Line 4:
Disallow: /wp-admin/
Disallow: /wp-includes/
<!-- WP Super Cache is installed but broken. The constant WPCACHEHOME must be set in the file wp-config.php and point at the WP Super Cache plugin directory. -->
