wordpress分类目录URL地址代码修改简化路径去掉category方法

这个方法可以将WORDPRESS的分类目录链接路径简化为，“www.***./目录/”格式，这样也更方便搜索引擎收录，起到优化SEO的作用。

如果你修改固定链接中的分类目录路径，没有起到作用，或者报404错误，那么你可以尝试如下方法：

将下列代码添加到functions.php文件中

//分类目录
/*
Plugin Name: WP No Category Base
Plugin URI: https://www.wodeai.net/archives/66643.html
Description: Removes '/category' from your category permalinks.
Version: 1.1.1
