typecho网站 rizhi主题的标题去掉分类名称的写法

typecho程序搭建的网站使用rizhi主题标题有个不好的地方就是会收录分类的名称：如下图：

这样很不利于seo优化，因为没有必要这样设置，而且如果我之前的页面标题是正常显示的话，使用这个主题会导致标题被简单修改，简单说就是多加了部分无用的标题，显然是多余的。

这样对于SEO优化是很不利的，所以就简单修改一下：找到主题的header文件，然后删除。

<?php if ($this->is('post')) $this->category(',', false);?>

这段代码删掉就可以了，如果不行，可以多试试附近的代码删减，记得备份。

下方就是备份的源代码：
