PHP Notices on /admin/config/people/user_readonly

saving the settings again from within Drupal 7 seems to get rid of these errors....

Now upon saving in D7, non of the profile fields are readonly any more....

actually the user upload and user email fields are readonly, all the profile fields are no longer readonly after saving in D7

actually all my profile fields are not on the config form, which is why their settings dissappeared, although they were hidden or readonly before I resaved in D7?

Oh so you have given up

  // The profile module is depr. in Drupal 7. See http://drupal.org/node/874026
  //if (module_exists('profile')) {
  //  $result = db_query('SELECT name, title FROM {profile_fields} ORDER BY category, weight, title');
  //  foreach ($result as $obj) {
  //    $fields[$obj->name] = $obj->title;
  //  }
  //}

Guess it is time to trash this module???

actually I have now migrated my profile fields into the user object, so it works fine for me know. I added new fields to the user and saved in a feature and ran a script like this:

/**
 * Migrate profile fields to user field api fields.
 */
function startupseven_update_7023() {
  $query = db_select('users', 'u');
  $query->leftJoin('profile_value', 'pv', 'u.uid = pv.uid');
  $query->leftJoin('profile_field', 'pf', 'pf.fid = pv.fid');
  $query->addField('u', 'uid');
  $query->addField('u', 'status');
  $query->addField('pf', 'name');
  $query->addField('pv', 'value');
  $query->condition('pf.name', 'profile_expertise','!='); 
  $query->condition('u.status', 1,'=');  
  $query->isNotNull('pv.value');
  $results = $query->execute();
  foreach ($results as $result) {
    $tablename='';
    switch($result->name){

also you could use the field permissions in D7 core?
