将此可配置产品添加到购物车，转到购物车页面并尝试更新数量，例如超过1。
但是在购物车页面中，如果我们尝试编辑数量，不会更新多个。但是在后端可以获得所需的数量。
Error : Number of quantity not available.
我们安装了一个扩展程序此错误来自扩展程序。如果我们删除扩展名，它将正常工作。但我们需要扩展用于某种目的。这是扩展程序的 observer.php 。

答案 0 :(得分：1)
检查产品是否有货。我正在检查Simple产品是否正常工作。仅可配置产品存在问题。我可以看到正在使用一个主题。也许这会导致问题。检查/ var / folders中的日志system.log和exception.log。这可能会有所帮助。
用于CART或CHECKOUT的任何扩展也可能导致问题。
