Question

我的托管服务已升级到PHP7.2，现在我开始遇到很多问题。由于我的Wordpress主题生成器不再存在，因此我自己解决了一些问题。由于某些原因，这种情况不会消失，我对此感到担心。

严重错误：耗尽的1048576000字节的允许内存大小（尝试分配20480个字节） /customers/3/8/4/XXX/httpd.www/wp-content/themes/dejavu/lib/classes/widget-popular.php 在第14行

每当我增加wp-config中的限制时，它就会不断增加。是该php文件中的问题，还是应该找别的地方？该php文件的内容：

<?php

升级到PHP7.2会导致内存问题
