Content profile bug - cannot edit user profile page
The Content Profile module associates a node with a user.  If the administrative user adds a profile node, then it is authored by the administrator.  Therefore, the user that the profile node was created for will not have access to edit the node since they are not the author.  As an administrator, make sure to change the "Authored by" field to be the user whose profile the node belongs to, then the user will have the ability to edit it.
