Wordpress wp-cron.php 执行不起作用

如何解决Wordpress wp-cron.php 执行不起作用

我有一个多站点 wordpress。我使用 WP Offload SES Lite 发送电子邮件。有一天电子邮件停止工作。

在 wp-ses 中，我看到许多电子邮件卡在队列中。发送测试电子邮件没有问题。

在调查这个问题后，我发现 wp-cron.php 不起作用。我尝试调试它并手动运行 wp-cron 并且没有与 cron 或 ses 相关的错误。好像没有运行。

尝试禁用 cron 并激活备用 cron，如下所示：

define('disABLE_WP_CRON',true); /** Use alternate WP_CRON method with
redirects. */ define('ALTERNATE_WP_CRON',true);

从 cli 和 url，通过浏览器和 Wget 运行它。

没什么。它在更新后一周左右开始发生。

我设置调试：

define( 'WP_DEBUG',true );
define( 'WP_DEBUG_LOG',true );
define( 'WP_DEBUG_disPLAY',false );
@ini_set( 'display_errors',0 );

这是我在运行 wp-cron 时看到的错误：

我已经安装了 wp cli，并进行了预制：

wp  cron event run --due-Now

结果如下：

PHP Notice:  Constant WP_DEBUG already defined in phar:///usr/local/bin/wp/vendor/wp-cli/wp-cli/PHP/WP_CLI/Runner.PHP(1197) : eval()'d code on line 97

看起来 cron 是 runnign，但是当我查看 Offload SES Lite DIAGNOSTIC 时

INFO I see this: 
WP Cron: disabled
Alternate WP Cron: Enabled
Last Run: 12:36:03 2021-01-07 UTC
Next Scheduled: 21:24:43 2021-01-30 UTC

看起来像通过电子邮件执行的 ses cron 没有发送也没有失败，他们只是停留在队列中。

我跑了：

wp cron test

得到：

PHP Notice:  Constant WP_DEBUG already defined in phar:///usr/local/bin/wp/vendor/wp-cli/wp-cli/PHP/WP_CLI/Runner.PHP(1197) : eval()'d code on line 97

任何想法可能是错误的？另外，我只需要电子邮件的 cron。有没有办法用cli运行wp-ses？

解决方法

我建议一一解决任何通知，并尝试构建解决方案。

示例：

注意：未定义变量：第 22 行 /var/app/current/wp-content/themes/my-theme/admin/product-search-fields.php 中的 post_id 警告：WP-Cron 生成成功但返回 HTTP 状态代码：403 Forbidden

文件 themes/my-theme/admin/product-search-fields.php 的第 22 行发生了什么？

当 cron(0 * * * ? *) 停止工作时，我在我的一个项目中遇到了类似的问题。我通过 Linux 服务器上的备用 cronjob 解决了这个问题。
