After installing Magento you need to set the Rating Visibility in the Admin panel. By default, ratings are not associated to any store view and the submit or a review will fail because of this.

 

To set the Rating Visibility do the following:

  1. Go to Catalog > Reviews and Rating > Manage Ratings
  2. Open each Rating Name and assign a store view
  3. Click the Save Rating button.

    Change:
    <active>true</active>
      To:
    <active>false</active>
  4. Save the file and refresh Magento cache (System > Cache Management)
