Lost the actual 'dashboard' permalink
The site has just been moved from the development domain to the 'www' domain, and now when I click "My Dashboard" I get a "Whoops - Page not found" 404 error. At the development site it works fine - so I guess I busted something when I did the move.
The permalink setting is /%postname%/ as generally recommended. It seems the actual permalink named 'dashboard' has gotten lost/disconnected. I've looked thru the database in wp_options and can't see anything wrong there.
We are trying to get the site live TODAY - so any and all help greatly appreciated.
