Cannot auto-update wordpress or plugins

Hi there,

I have just auto-updated three sites to 3.2 without any problem. The fourth gives me this message:

No Results Found
The page you requested could not be found. Try refining your search, or use the navigation above to locate the post

I have tried multiple times and have turned off all my plugins. One of my sites actually uses the identical theme. That one had no issues.

My plugins will not update either. I have called my host and they said everything is up to date and working fine.

The site is https://intheknowtraveler.com

Any help is appreciated.
