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:
- Go to Catalog > Reviews and Rating > Manage Ratings
- Open each Rating Name and assign a store view
- Click the Save Rating button.
How to disable Reviews & Rating
To disable Product Reviews please follow these steps:
- Navigate to System > Configuration > Advanced
- Set "Mage_Rating" and "Mage_Review" to Disable and click "Save Config" button
- Open the following file: /app/etc/modules/Itactica_ExtendedReviews.xml
- Save the file and refresh Magento cache (System > Cache Management)
