嗨

今天，我在wp-admin和wp-login.php中的wordpress博客出错了。

如何修复此错误请注意，我无法登录到该站点，非常感谢

造成这一错误的主要原因是，在您的站点的某个地方，它可能是您的主题或插件，有人错误地使用了某些功能。

错误消息本身很好地描述了这个问题：

1. 脚本和样式不应该在wp_enqueue_scripts、admin_enqueue_scripts或login_enqueue_scripts挂钩之前注册或排队。
2. 不要在管理区域取消jquery脚本的注册。若要针对前端主题，请使用wp_enqueue_scripts挂钩。

所有其他错误都是由于前4条错误消息被提前输出而引起的，并且在前4条被解析后就会消失。

这意味着有人为排队和退出队列脚本添加了代码，这些代码看起来可能很像这样：

wp_deregister_script( 'jquery' );
wp_register_script( 'jquery', 'some/url/here', ...);
wp_enqueue_script( 'jquery' );

造成这些错误的原因是，这些函数显然只是访问了functions.php或插件文件，而没有正确地使用钩形。

至少，它应该是这样的：

function wpse_329345_bad_jquery_nonsense() {
    wp_deregister_script( 'jquery' );
    wp_register_script( 'jquery', 'some/url/here', ...);
    wp_enqueue_script( 'jquery' );
}
add_action( 'wp_enqueue_scripts', 'wpse_329345_bad_jquery_nonsense' );

首先，我要查找有问题的代码(如果其他人正在处理站点)是主题目录中的functions.php文件的底部。如果您找到它，可以在我的示例中看到我所做的更改(或者删除它，因为您应该使用不是在排队等待你自己的jQuery)。这应该能解决这个问题。

都是这么说的。这些只是调试消息，目的是通知开发人员他们做错了什么。出现这些情况是因为您已经在站点上启用了调试。如果您的站点处于活动状态，则不应启用可见的调试消息。您可以通过禁用WP_DEBUG来做到这一点。启用它的说明是这里。遵循这些，但是将值设置为false而不是true来禁用它。
