Admins cannot do this directly.
Please follow either of the 2 methods bellow to resolve.
- The user themselves creates a login, applies for membership of your site and you merge the two records.
- You add (or remove, save and re-insert) their email address in the TMP record that you already have; that sends an invite to them to turn that record into their own login. Once they have followed the instructions on the invite and created their account, the user will then no longer be displayed as a TMP record and you will be able to add roles to that user.
Please note if you are assigning an admin role to a user this needs to be done from a laptop/ desktop, the role cant be assigned via a mobile or tablet, also users will need to login to a laptop/desktop to accept the role via clicking on site administration.
