Notice: Uninitialized string offset: 0 in basic_id_safe() (regel 120 van /var/www/d7/sites/all/themes/basic/template.php [#1356236]

I get the following error on enabling the Basic theme on my D7 website

Notice: Uninitialized string offset: 0 in basic_id_safe() (regel 120 van /var/www/d7/sites/all/themes/basic/template.php

It refers to is

function basic_id_safe($string) {
  // Replace with dashes anything that isn't A-Z, numbers, dashes, or underscores.
  $string = strtolower(preg_replace('/[^a-zA-Z0-9_-]+/', '-', $string));
  // If the first character is not a-z, add 'n' in front.
  if (!ctype_lower($string{0})) { // Don't use ctype_alpha since its locale aware.
    $string = 'id'. $string;
  }
  return $string;
}

Also am seeing this error. After a little research found that there are some new functions in D7 that handle cleaning up classes. Replacing the above function with this seems to do this trick:

function basic_id_safe($string) {
  // Replace with dashes anything that isn't A-Z, numbers, dashes, or underscores.
  $string = drupal_html_id($string);
  return $string;
}
