我在Magento 1.5.0.1商店看到一个问题，某些产品的库存被覆盖为0。这似乎是自动发生的，我无法弄清楚为什么。我最近安装了来自Tinybrick的Lightspeed和SpeedBooster，这可能与它有关，但我已经禁用它们但仍然没有运气。我真的很茫然，所以任何想法，想法或调试技巧都会非常感激。
谢谢！

答案 0 :(得分：1)
在产品和库存对象上放置一个前后保存事件侦听器。
让听众检查股票是否为“0”。
如果检测到零库存，则通过debug_backtrace中的信息构建堆栈跟踪。您需要手动创建它，因为回溯的参数中的循环引用可能会创建无限输出。
使用回溯确定股票被设置为零的位置/时间。
