Content profile bug - cannot edit user profile page If the administrator user creates a profile node for a user, then that user cannot edit his own profile. How can I solve this problem? I have looked on the Content Profile module's issues, and found similar problems but no solutions for that.

In my case, that user created his profile node by himself, but I changed his username through phpmyadmin; now, his profile node results created by the admin user, not himself.

Problem solved! that profile node had php input format and that user whom i edited profile hadn't access for php input format filter.
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.
