解决wordpress中文标签无法访问报500错误的问题

首先打开Wordpress站点下wp-includes目录里的class-wp.php文件。操作之前复制备份一个是好的习惯。
搜索$_SERVER[‘REQUEST_URI’]。用“//”注释掉

//list( $req_uri ) = explode( ‘?’, $_SERVER[‘REQUEST_URI’] );注释掉这一行，添加下面两行代码

$Temp_REQUEST_URI= mb_convert_encoding($_SERVER['REQUEST_URI'], "UTF-8", "GBK");
list( $req_uri ) = explode( '?', $Temp_REQUEST_URI );

搜索$_SERVER[‘PATH_INFO’]。用“//”注释掉此行：

//$pathinfo = isset( $_SERVER[‘PATH_INFO’] ) ? $_SERVER[‘PATH_INFO’] : ”;注释掉这一行，添加下面两行代码

$Temp_PATH_INFO = mb_convert_encoding($_SERVER['PATH_INFO'], "UTF-8", "GBK");
$pathinfo = isset( $Temp_PATH_INFO ) ? $Temp_PATH_INFO : '';
