Help – Can't login to wordpress

I get the following error on my login screen:

That ‘redirect_uri’ isn’t allowed for that client_id.
A password will be e-mailed to you.

I disassociated accounts that were not me from my facebook book (i.e. obviously I didn’t want people that were not me to be associated to my fb account).

Once I did that, I can no longer login. Every time I go to:
https://www.planetsteelers.com/steelersblog/wp-admin/ or
https://www.planetsteelers.com/steelersblog/wp-login.php?action=login or
https://www.planetsteelers.com/steelersblog/wp-login.php

it redirects me to the register page (see below) w/ the error message list above… please help.

NOTE: I am using simple facebook connect amongst about a dozen other plugins
