I did a script upgrade from 1.4.1 to 1.4.2 and the frontend/backend works find, but when I viewed the frontend catalog product page, the product image and add cart button is missing and it showed the following:
Fatal error: Class ‘Mage_CatalogInventory_Helper_Minsaleqty’ not found in .../public_html/app/Mage.php on line 520
When I looked at the mage.php, here is what it lookslike on line 520
Can anyone help to fix it please? I reindexed the catalog and no help there.
