typecho根目录下生成一个error_log文件
内容为：

可否在/var/Typecho/Plugin.php文件中增加这一句？
error_reporting( E_ALL & ~E_STRICT );这样有没有用，会不会对程序有影响？
抑制错误的输出应该是治标不治本的~
而且尽量不要动核心代码，不然以后程序更新的时候可能会有意想不到的结果
所以我们应该从错误的根源入手：
这个报错是因为 Avatars 插件里面的 avatars() 函数没有声明成静态函数，而用 Avatars_Plugin::avatars() 的时候访问的是静态函数所以就出问题了，所以直接在 avatars 插件的 plugins.php 的 avatars 函数前面加一个 static 关键字就不会报错了
去下载了个 Avatars 插件看了看，应该是在 plugins.php 的 109 行，
把
public function avatars($size,$rating,$default,$comments){改成
public static function avatars($size,$rating,$default,$comments){就可以啦
