404 for post_status-sitemap.xml

I’m getting the following error through Google Webmaster Tools:

*General HTTP error: 404 not found*
Sitemap: http://www.fearlessfresh.com/post_status-sitemap.xml
HTTP Error: 404

I’ve followed all of your KB troubleshooting steps, and even had my host (Copyblogger Synthesis) troubleshooting from their end. We can’t figure out what’s causing the problem. Synthesis Support finally gave up and told me to contact you directly.
