【发布时间】：2019-01-08 10:38:24
【问题描述】：

我的网站突然出现了一些问题，没有任何已知的变化。最突出的是，没有出现子菜单。 html 就在那里，一切似乎都在管理面板中的 wordpress 中进行了正确设置。但是悬停时不会出现子菜单。网站是 btwimages.com。

【问题讨论】：

你安装了新插件吗？
仅仅发布一些 HTML 并不能真正帮助我们帮助您。我们不知道您的子菜单应该如何工作，如果它使用 css-hover、js 或者上面的 html 是否正确。是插件吗？自定义代码？请阅读：How to create a Minimal, Complete, and Verifiable example 和 How do I ask a good question?
另外，当你说 “wordpress 管理面板中的所有内容似乎都存在”时，你的意思是什么。 “一切”像什么？
实际菜单结构使用带有子项的 wordpress GUI 和所选位置。页面源代码中的 HTML 在那里。什么都没有改变。

标签： php wordpress drop-down-menu

【解决方案1】：

如果您无法通过管理面板修复它，您可以将此代码添加到页眉或页脚：

jQuery('.menu-item-has-children').hover(function() {
    jQuery('.menu-item-has-children .sub-menu').css('display', 'none');
    jQuery(this).find('.sub-menu').css('display', 'block');
});

【讨论】：

似乎仍然没有帮助。甚至当我登录 wordpress 并查看该网站（上面带有编辑页面的黑条）时，该网站顶部的管理栏也没有出现。
我的 footer.php 似乎没有加载，有什么想法吗？
@TJWJR 似乎代码中某处出现错误，导致某些脚本无法运行。尝试启用调试模式以查看问题
@TJWJR 我检查了你的网站，子菜单已经在工作了，嗯？
