I changed my site/WP Address by mistake and now I can't login to fix it. I tried following the steps here http://codex.wordpress.org/Changing_The_Site_URL
After following those steps, I can get back to the WP login by going to http://www.example.org/example/wp-login.php, but it just goes on an infinite login loop. When I go to my actual website, it won't open due to too many "redirects". What do I do to fix this?
