[Plugin: Redirection] Homepage redirects to 404 page

My site is doing this also.. I added a page. For somereason it became the home page.
http://www.silverisundervalued.com/
redirects to http://www.silverisundervalued.com/opt-in-form

I trashed the page and the homepage continues to redirect to
http://www.silverisundervalued.com/opt-in-form
I deleted the .htaccess file
did a chmod to 666 and 777. there seem to be no issues there.

Not sure where to look.

I even turned off all the plugins and changed the theme and the domain still redirects to
http://www.silverisundervalued.com/opt-in-form
which does not exist.
