Some times Magento users get 404 errors on Product Pages. Usually when you click on sample products which are displayed in Home Page, it gives 404 Error.
Don’t panic, if you are also receiving the same error. In order to deal with such issue, you need to go to phpMyAdmin and run following command:
INSERT INTO `report_event_types` (`event_type_id`, `event_name`, `customer_login`) VALUES (1, 'catalog_product_view', 1), (2, 'sendfriend_product', 1), (3, 'catalog_product_compare_add_product', 1), (4, 'checkout_cart_add_product', 1), (5, 'wishlist_add_product', 1), (6, 'wishlist_share', 1);
Also getting 404 Error after Magento 1.7 Upgrade?
