System uses MysqlManager.php instead of MysqliManager.php

This is what I have

  'dbconfig' =>
  array (
    'db_host_name' => 'localhost',
    'db_host_instance' => 'SQLEXPRESS',
    'db_user_name' => 'root',
    'db_password' => '******',
    'db_name' => 'suitecrm',
    'db_type' => 'mysql',
    'db_port' => '',
    'db_manager' => 'MysqliManager',
  ),

Note that you should have the “i” in db_manager, but the db_type is simply “mysql” (don’t add an “i” there!)
