How should I change the permissions PRIVATEMSG for users in order them to have the access? Good day,
I've marked read, write and delete the privatemsg for the authenticated users but they don't still have access to the pages such as user/user-id/messages. The access is only granted with "read all" permission.
I use privatemsg 6.x-1.5
Thanks.
The normal user interface is at /messages, user/uid/messages is only meant to read messages of other users and is not a full replacement.

6.x-2.x has a feature that allows to move it around but it's relatively complex and I wouldn't necessarly recommend using.
