internal links break

I believe that WPFC is somehow “breaking” my internal links. Here’s what happens: I edit a page, then I delete the cache manually. By the next day, there are multiple internal links to my pages that redirect to the home page. If I delete the cache manually again, everything is fixed.

The site is set to clear cache once per day.
