WooCommerce产品在实际没有缺货时显示“缺货”消息

客户网站出现问题，其中产品随机显示

“此产品目前缺货，缺货。

问题是我们没有打开库存跟踪，所有产品都应该一直有库存。

当我进入WordPress管理员并单击产品的更新按钮（不更改任何内容）时，消息就会消失，“添加到购物车”按钮会按预期显示。不幸的是，将来这些问题会在这些项目上重复出现，要修复它，我必须再次更新产品（同时单击WooCommerce设置中的更新可以暂时解决问题）。

我需要找到一种方法来永久解决此问题，以便它不会自行恢复。

网站详情：

• 使用 WordPress 3.9.1
• WooCommerce 2.1.12
• PHP 5.3.10 （也尝试本地使用 5.5.10）

我尝试了什么

• 删除除WooCommerce之外的所有插件
• 更改主题（尝试了所有标准的WordPress主题和一些WooThemes主题，但无济于事）
• 更新了WooCommerce（它是v 2.1.5）
• 手动插入到wp_postmeta添加元键并将其设置为（如我们在一些工作产品中观察到的那样）_manage_stockno
• 手动插入到wp_postmeta添加元键“_stock”并将其设置为（如我们在一些工作产品中观察到的那样）0
• 比较了点击更新按钮之前和之后产品的后期版本，以观察是否有任何更改会导致问题...无
• 未打开缓存
• 使用 XDebug 跟踪 和 中的变量。$available_variationsvariable.phpclass-wc-ajax.phpclass-wc-product-variable.php

在调试时，我注意到在正在工作的产品中，变量包含2个数组，其中填充了产品信息，但是在没有填充产品信息的产品上，它是一个空数组（这导致缺货消息显示为由 ）。单击更新按钮，然后跟踪变量，可以正确显示信息。$available_variationsvariable.php

老实说，在这一点上，我不知所措。我认为问题出在两门课的某个地方，但我无法分辨。

还有其他人对此有问题吗？解决此问题的任何方法，因此我不必继续为此客户端更新产品。

错误日志我向产品变体类添加了错误日志。结果如下：

对于具有“缺货”消息的产品，日志中不显示任何内容。

<h2>What are The Basement Tapes?</h2>
<em>The Basement Tapes</em> are conversations between Dr. R.C. Sproul Jr., Rev. Laurence Windham, their friends and special guests, on subjects related to the “good life,” a simple, separate, and deliberate life, lived out for the glory of God and for the building of His Kingdom.

You might even say that the Basement Tapes serve to help us develop a Christian worldview. Started in 2002, we now have over #140 conversations on all areas of life that we are seeking to think biblically about so that we might take dominion over them for the King and His kingdom.

潜在的后续步骤如果我不能解决这个问题，我的下一个想法是编写一个脚本，该脚本将每晚浏览并更新网站上的每个产品（因为临时修复似乎至少适用于我们的24个）。虽然如果我能节省一些时间，我宁愿不要其他人能够永久解决这个问题。

更新于 2014 年 10 月 23 日

尽管尝试了以下答案，但此问题仍然存在。我创建了一个日志记录插件，希望有助于跟踪缺货消息的频率，并希望帮助将消息与网站上发生的任何操作相关联。它目前已针对此特定网站进行了定制，但我正在开发一个版本，以便与大家共享，以便即使我找不到答案，也可以。
