I've had a rather frustrating thing happen to one of my WP sites (spirituality2012.com) where I'm unable to access the Dashboard, wp-admin or indeed any part of the back-end of the site.
I've added a Login Box to the footer, so I'm able to login, but I'm redirected to the page I was already on. Clicking the 'edit' link on a page results in a 404, as does trying to navigate to wp-admin.
However, wp-login.php does seem to be ok though it takes me back to the home page after loggin in.
Can't get my head around this, and I've had a look in the forums but can't find an answer, so any thoughts would be greatly appreciated.
