我收到如下错误，我不知道如何解决这个错误，因为我是magento的新手。如果有错误格式的描述，它也会帮助我。我无法解决这个问题的主要原因是因为我首先不理解这个错误。

这似乎是在启用Flat Categories和/或Products并且块调用产品集合的addAttributeToSort（）时发生的Magento错误。 'order by'子句中的列应该是cat_index.position而不是cat_index_position。
我发现this extension声称要解决这个问题，虽然我还没有测试过它。
Mage_Catalog_Model_Layer-> getFilterableAttributes（）。
导致此查询。
我建议你重新索引属性，然后再次检查。
可能您已添加或删除了某些属性，并且DB逻辑关系不到位。
如果这不起作用，那么您需要检查处理属性的社区模块。
