Revert home page from another page

I seem to have messed something up on the home page.  I was messing around with some of the login widgets, and I did something where I can access the home page, but once I login, the site fails to load because of some sort of infinite redirection loop.

I'd like to revert the home page and get rid of the widgets - I can add them back again.  The problem is, I can't even load the configuration panel from the home page and therefore can't access the edit this page panel.

Any thoughts?
