    if ($this->is_admin() || isset($_REQUEST['dbg'])) {

The expression $this->is_admin() of type integer|null is loosely compared to true; this is ambiguous if the integer can be 0. You might want to explicitly use !== null instead.

      echo "debug_backtrace (administrator only): \n\n ";
      echo '<pre>';
      var_dump(debug_backtrace());

var_dump(debug_backtrace()) looks like debug code. Are you sure you do not want to remove it?

      echo '</pre>';

    // is redundant.

    // Renumber backtrace items.
    //$trace = preg_replace('/^#(\d+)/me', '\'#\' . ($1 - 1)', $trace);
