forgot password not working

indeed there is an issue for Commerce Checkout Redirect module
it replaces the submit function

/**
 * Implements hook_form_FORM_ID_alter().
 */
function commerce_checkout_redirect_form_user_pass_alter(&$form, &$form_state) {
  if (arg(0) == 'checkout' && arg(2) == 'user' && arg(3) == 'password') {
    $form['#submit'][0] = 'commerce_checkout_redirect_user_login_submit';
  }
}

this should be

/**
 * Implements hook_form_FORM_ID_alter().
 */
function commerce_checkout_redirect_form_user_pass_alter(&$form, &$form_state) {
  if (arg(0) == 'checkout' && arg(2) == 'user' && arg(3) == 'password') {
    $form['#submit'][] = 'commerce_checkout_redirect_user_login_submit';
  }
}

here is a gerrit commit that uses an updated patch for the Commerce Checkout Redirect, about user password recovery (#1677106-4: Add user password recovery support.).
