Magento的：项目（Mage_Customer_Model_Customer）重复的问题？(Ma

我最近在我的店里ecomerce Magento的升级，从Magento 1.9至1.9.1 。网站升级后工作正常，但是从管理控制台中添加客户时，现在我看到一个奇怪的问题。

同时加入的客户，我店选择id作为Admin如下图所示：

如果我选择Main Website相关联的网站，那么它的工作原理确定，但我只是想知道为什么它不工作，并给予错误与“管理”，而在另一家商店Magento的，我没有看到这样的问题。

我收到以下错误：

我想此修复程序： https://support.webcto.eu/index.php/Knowledgebase/Article/View/50/8/item-mage_catalog_model_product-with-the-same-id-already-exist它是工作，但我不认为这是修改Magento的主要核心不错的主意。

请检查并建议我能做些什么来解决这个问题？
