php // Ver1.0.8 Line 254-379 echo <<<EOF ... <a href="$dir/$file" class="clearfix" data-name="$file"> ... EOF;
(2) When the site root is not in the directory of index.php When you click "首页", you will jump to the root directory, resulting in 404 or 403
For Example,if your index.php is in localhost/file,click "首页" in index.php or error/FILE-404.php,then you will skip to localhost/index.php
