404 not found after i created an new user account?

Hello Admin,

404 not found after i created an new user account?

Means i had created a new account directly from my super admin panel

this was the new account i had created : “cinderela” and the site is: http://blog.prosper8dotcom.com/cinderela/

But i am wonder that i cannot open each menu, always the 404 comes.

I already open the GRANT ACCESS why this happening to my new user account.

Please help.

Thank you.
