Redirected to a 404

Hello
I have installed the Customer Portal plugin as well as the free User registration plugin.
I have created pages to all users
and then edited and updated a page of one specific user
I then created a new page for login
and used the short code there:
[wppb-login redirect_url=”http://www.yourdomain.com/private-page”%5D

When I login in that page with the user details (the same one I updated its private page) I get redirected to a 404 page

note – I am using lifterlms in my site.

Can you help
Thanks
Ziv
