Question

我正在将 magento 企业版迁移到社区版。我马上就好。但是后端只有一个问题。如果我去管理产品并单击任何产品，我就会收到此错误。

致命错误：在第 146 行的 magento\lib\Varien\Data\Form\Abstract.php 中找不到类“Mage_Enterprise_Rma_Block_Adminhtml_Product_Renderer”

Answer 1

在您的数据库中找到“eav_attribute”表并删除带有属性代码“is_returnable”的行

Answer 2

解决方案：

使用它进行降级，那么一切都会好起来的：

    DELETE FROM eav_attribute WHERE `attribute_code` = 'giftcard_amounts';
    DELETE FROM eav_attribute WHERE `attribute_code` = 'related_tgtr_position_limit';
    DELETE FROM eav_attribute WHERE `attribute_code` = 'related_tgtr_position_behavior';
    DELETE FROM eav_attribute WHERE `attribute_code` = 'upsell_tgtr_position_limit';
    DELETE FROM eav_attribute WHERE `attribute_code` = 'upsell_tgtr_position_behavior';
    DELETE FROM eav_attribute WHERE source_model LIKE 'enterprise_%';
    DELETE FROM eav_attribute WHERE backend_model LIKE 'enterprise_%';
    DELETE FROM eav_attribute WHERE attribute_code IN ('gift_wrapping_available', 'gift_wrapping_price');
