Magento error "There are no products matching the selection"

After adding products I had a problem. The home page shows "There are no products matching the selection". So I did the following steps and it worked for me.

Solution:

Please check following settings are done for your product

1. The products must be Visible in Catalog.
2. The products must be Enabled.
3. Product must have a stock Quantity.
4. The product must be set to In Stock.
5. If the product is set not to track stock, it still need to have a stock Quantity and be set to In Stock.
6. The product must be assigned to the target Category.
7. If using multi-website mode (or if you imported the products through Data Flow), the products must be assigned to the target Website.
8. You must refresh your “var/Cache” & rebuild all indexes from admin > system > index management

Hope this helps you.
