可配置产品未在购物车中更新

Question

请访问此link

将此可配置产品添加到购物车，进入购物车页面并尝试更新数量，例如超过 1 个。

但是在购物车页面中，如果我们尝试编辑数量，它不会更新超过一个。但所需数量的数量在后端可用。

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，它会正常工作。但我们出于某种目的需要该扩展名。这是扩展的observer.php。

检查产品是否有库存。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主题。也许这就是问题所在。检查 /var/ 文件夹中的日志 system.log 和 exception.log。这可能会有所帮助。

用于 CART 或 CHECKOUT 的任何扩展也可能会导致问题。
