My Magento site has a problem with Special Price. In the database, the
special_price column shows a null value, but in the Magento backend (Manage Product -> Special Price) it shows 0.00 instead of NULL.
It also shows the Special Price as 0.00 instead of the original value in the product detail page. Whenever user add product to cart it gives a price of 0.00.
How do I remove the special price of 0.00 from the backend and front-end?
