Google encountered 404 Crawl errors in my Website - Need Help

[bustani100]

Crawl errors - issues Google encountered when crawling my site:seekriches.net has resulted in 1,434 URLs not found.

I have read the Bluehost FAQs and checked for similar issues:
My site's URL (web address) is:seekriches.net and problem was detected on July 4, 2011

I do not know how this came about. I cannot locate the sitemap listing these URLs and therefore I'm unable to remove them.

Will be grateful to help on what I could possibly do to restore the functioning of my site.

Thanks

There are plenty of errors in your website when I see just the basics.

1) Your sitemap plugin is misconfigured: Error loading stylesheet: An unknown error has occurred (805303f4)
2) Your robots.txt is not configured properly. You can check it at http://tool.motoricerca.info/robots-checker.phtml
