we just need some help. everytime a customer login to our customer login page and if they type their password incorrect, the template of our login page disappeared

Another Issue: If a customer submits a product review it wont show a success message like "Thank you for your review. It has been submitted to the webmaster for approval." It does get submitted to the admin and I can see it come through but the customer cannot see any kind of success message.
