You need to look in the file "includes/config.php" for a section like this:
PHP Code:
// ****** USERS WITH ADMIN LOG VIEWING PERMISSIONS ******
// The users specified here will be allowed to view the admin log in the control panel.
// Users must be specified by *ID number* here. To obtain a user's ID number,
// view their profile via the control panel. If this is a new installation, leave
// the first user created will have a user ID of 1. Seperate each userid with a comma.
$config['SpecialUsers']['canviewadminlog'] = '1';
// ****** USERS WITH ADMIN LOG PRUNING PERMISSIONS ******
// The users specified here will be allowed to remove ("prune") entries from the admin
// log. See the above entry for more information on the format.
$config['SpecialUsers']['canpruneadminlog'] = '1';
// ****** USERS WITH QUERY RUNNING PERMISSIONS ******
// The users specified here will be allowed to run queries from the control panel.
// See the above entries for more information on the format.
// Please note that the ability to run queries is quite powerful. You may wish
// to remove all user IDs from this list for security reasons.
$config['SpecialUsers']['canrunqueries'] = '1';
// ****** UNDELETABLE / UNALTERABLE USERS ******
// The users specified here will not be deletable or alterable from the control panel by any users.
// To specify more than one user, separate userids with commas.
$config['SpecialUsers']['undeletableusers'] = '';
// ****** SUPER ADMINISTRATORS ******
// The users specified below will have permission to access the administrator permissions
// page, which controls the permissions of other administrators
$config['SpecialUsers']['superadministrators'] = '1';
For each category, put the comma delimited list of users by userid you wish to have those permissions/attributes. Bear in mind any admin with access to the server can alter this file as well.
