所以周六，我的magento ishop发生故障，我无法将任何产品添加到购物车中。
当我点击“添加到购物车”时，它会将我重定向到购物车并说：
“无法将商品添加到购物车。”
这是我的日志：

我真的希望，有人会想出一些东西。

我以前见过这个问题。当数据库被写入Magento API之外并出现问题时，就会发生这种情况。一个简单的解决方案是打开MySQL常规日志以记录所有SQL查询。在命令行上使用tail程序和-f标志实时查看mysql常规日志，如tail -f general.log
现在尝试执行给出完整性约束违规的操作，您应该在日志中看到尝试的sql查询。使用此信息，您应该能够更好地跟踪问题，并在需要时删除数据库中的错误条目。
有时它是由于与产品相关的扩展而发生的。在这种情况下，请禁用所有第三方扩展程序，然后尝试添加产品。
