Permalinks 404

Hello all,

We’ve created a dev version of a site — http://richa.blueoceanideas.net/ and we’re moving it to it’s domain — http://www.richarealestate.com

However, if you go to the domain none of the links work. I’ve changed the options in General Settings to reflect the new domain and yet we still receive 404. We also receive the “too many redirects” I’ve tried:
– disabling all of the plugins (when I do, I disable “Disable Canonical URL Redirection” and receive the too many redirects error
– changing/default permalink settings
– deleting .htaccess and allow WP to remake it
– going back to the default WP theme
– searching all of the files and DB for ‘richa.blueoceanideas.net’

I’ve also gone into the DB and changed the GUID of each row in wp_posts. Creating a new page is visible on the subdomain ( http://richa.blueoceanideas.net/testo ) but not on the domain ( http://www.richarealestate.com/testo ).

Any ideas?
