[Plugin: WordPress SEO by Yoast] My Sitemaps are gone REALLY need Help!

Hi,

I just noticed last night that my sitemaps were gone. I tried deactiving the plugin I updated my permalinks but nothing is helping.

I went through each settings page and clicked on save but no luck. I don’t know what to do as this is really going to kill my rankings.

This is my site: Positive Thinking
Any help would be appreciated.

Thank you!
Howard
