我运行以下命令编写器更新，现在正在工作。如果它不能解决你的问题，增加你的内存限制在memory_limit在php.ini文件。

It is unfortunately easy to program in PHP in a way that consumes memory faster than you realise. Copying strings, arrays and objects instead of using references will do it, though PHP 5 is supposed to do this more automatically than in PHP 4. But dealing with your data set in entirety over several steps is also wasteful compared to processing the smallest logical unit at a time. The classic example is working with large resultsets from a database: most programmers fetch the entire resultset into an array and then loop over it one or more times with foreach(). It is much more memory efficient to use a while() loop to fetch and process one row at a time. The same thing applies to processing a file.

Wordpress用户添加一行:

@ini_set（“memory_limit”、“-1”）;

在wp-settings.php中，你可以在wordpress安装的根文件夹中找到

如果你想读取大文件，你应该一点一点地读取，而不是一次读取。 这是一个简单的数学:如果您一次读取一个1mb大的文件，那么同时至少需要1mb的内存来保存数据。

所以你应该使用fopen & fread一点一点地阅读它们。

在Wordpress中切换到一个新主题后，我收到了同样的错误信息。PHP运行的是5.3版本，所以我切换到了7.2。这解决了问题。

我没有更新主机，数据库是只读的。Joomla需要编写会话，但无法完成。
