我正在一个 WordPress 多站点网络上运行 WP-Discourse 插件。网络中的两个站点使用它为两个不同的 Discourse 站点进行 SSO。其他网络站点不使用该插件。它在 2.4.6 版本之前运行正常，但在此之后会导致整个网络出现严重错误。在 2.4.7 更新失败后，我等到下一个版本再次尝试，但问题相同。 该网络运行 WordPress 5.4.1 和 PHP 5.6.40。我提到这一点是因为我知道两者都已过时，但我们有不能升级的原因。 我需要怎么做才能解决这个问题？感谢任何指导或提示。 ---

我的意思是，我对此并不感到自豪，但多站点网络中存在一些无法更新的主题，并且在我们尝试更新 WordPress 或 PHP 时会导致问题。就我所知，我们非多站点的网站都保持最新，只有多站点是一团糟…… ---

我什么都不知道，但我曾在 WordPress 上遇到过非常类似的错误，当时 PHP 版本太旧（或者有时太新，那也会有问题）。 ---

> [@John-ISMRM](#): > > `undefined function register_block_type_from_metadata()` 该函数是在 Wordpress 5.5.0 中[引入](https://developer.wordpress.org/reference/functions/register_block_type_from_metadata/)的，所以问题就在这里。Wordpress 5.5 已经有 2.5 年多的历史了。您真的应该解决阻碍您升级的“原因”并升级 Wordpress（和 PHP）。 要么是插件，要么是 Wordpress 主题会出问题，而这个主题是无法在当前 Wordpress 上运行的。所以直说吧，这是主题的问题，而不是 [WP Discourse](https://github.com/discourse/wp-discourse) 插件的问题。 ---

> [@RGJ](#): > > 该函数是在 Wordpress 5.5.0 中[引入](https://developer.wordpress.org/reference/functions/register_block_type_from_metadata/)的，所以就是这样。Wordpress 5.5 已经发布两年半了。 如果真是这样，并且没有打算像以前那样向后兼容，那么[WP-Discourse 插件页面](https://wordpress.org/plugins/wp-discourse/)就需要更新为“需要 WordPress 版本：5.5 或更高版本”。它目前显示的是“4.7 或更高版本”。 ---

我不知道你使用的是什么WordPress主题，但 **有时** （我经历过），让主题兼容PHP 7+只需几行代码即可修复。
