Warning: Cannot modify header information - headers already sent by (output started at /.../public_html/wp-config.php:1) in /.../public_html/wp-includes/pluggable.php on line 890
pluggable.php 这个文件其中一部分内容
function wp_redirect($location, $status = 302) {
global $is_IIS;
$location = apply_filters('wp_redirect', $location, $status);
$status = apply_filters('wp_redirect_status', $status, $location);
if ( !$location ) // allows the wp_redirect filter to cancel a redirect
return false;
$location = wp_sanitize_redirect($location);
if ( $is_IIS ) {
header("Refresh: 0;url=$location");
} else {
if ( php_sapi_name() != 'cgi-fcgi' )
status_header($status); // This causes problems on IIS and some FastCGI setups
header("Location: $location", true, $status); （这是890行）
}
}
前台没问题,后台出现这问题

DW编辑文件的话默认貌似不是utf8无bom,你检查一下编码,这毛病通常是因为括号里那个文件由于有bom多出一个看不见的空格

括号里面那个文件是不是用记事本编辑过了？用专门的编辑器存成utf8无bom或者记事本存成ANSI格式后面应该还有哪个文件引起的这个问题,你重点看下那个我没动过这个文件，一般打开文件也是用DW，我百度搜了类似的问题，都是这样说的，不懂php，所以还是不明白，能详细解答下吗？...

我的也有这样提示，不过我是把Auto Blogroll 插件停用就可以了！不信你可以试试！
