seems I'm not the only one with this problem: http://wordpress.org/support/topic/main-page-redirecting-for-no-reason
I had Redirection working no problem. But when I posted my newest post today, my homepage, a static page, automatically began redirecting to the lastest post page.
I switched to Simple Redirects 301 as the above link suggested, but prefer the Redirection plugin with it's logging. Any known fix for this?
