我在尝试登录管理面板时遇到了这个错误。我无法理解它。

Warning: Cannot modify header information - headers already sent by (output started at /home/xxxxxx/public_html/wordpress/wp-config.php:1) in /home/xxxxxx/public_html/wordpress/wp-includes/pluggable.php on line 881

可插入的.php 881:

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 ( !$is_IIS && php_sapi_name() != 'cgi-fcgi' )
status_header($status); // This causes problems on IIS and some FastCGI setups

header("Location: $location", true, $status);
}
endif;

我使用的是最新版本的 wordpress 3.4.2。我的网站似乎工作正常,但错误阻止我进入登录页面,这意味着我根本无法管理或卸载似乎触发了此问题的插件 (dbc backup 2)。我已经用 HTML-kit 工具检查了 wp.config 文件数百次,在文件的开头和结尾都没有可见的空格。我有:

  1. 使用 HTML-Kit 工具检查 wp-config 文件中的空格
  2. 下载并插入新的 wp-config 文件
  3. 通过重命名禁用插件目录

...错误仍然存​​在

我唯一要尝试的是有人在 wordpress 论坛上发布的代码,声称他通过将以下代码插入 wp-config.php 文件解决了这个问题:

    <?
//dont use header function in wordpress-wp_signup.php
global $domain;
global $path;
//change urlnew variable as per requirment
$urlnew = "http://".$domain.$path."/wp-admin/admin.php;

echo "<script>";
echo "location = '$urlnew';";
echo "</script>";
echo $urlnew;
?>

我不愿意添加代码,因为我不熟悉 html 或 php,而且我不完全理解这段代码的功能,也没有详细的说明将它准确地放置在何处。有更好的建议吗?


Themes function.php 文件是这样结尾的,到底应该在哪里插入代码呢?:

// include custom widget

$temp_root = get_root_directory('include/plugin/custom-widget/custom-blog-widget.php');

include_once($temp_root . 'include/plugin/custom-widget/custom-blog-widget.php');

$temp_root = get_root_directory('include/plugin/custom-widget/custom-port-widget.php');

include_once($temp_root . 'include/plugin/custom-widget/custom-port-widget.php');

$temp_root = get_root_directory('include/plugin/custom-widget/custom-port-widget-2.php');

include_once($temp_root . 'include/plugin/custom-widget/custom-port-widget-2.php');

$temp_root = get_root_directory('include/plugin/custom-widget/popular-post-widget.php');

include_once($temp_root . 'include/plugin/custom-widget/popular-post-widget.php');

$temp_root = get_root_directory('include/plugin/custom-widget/contact-widget.php');

include_once($temp_root . 'include/plugin/custom-widget/contact-widget.php');

$temp_root = get_root_directory('include/plugin/custom-widget/flickr-widget.php');

include_once($temp_root . 'include/plugin/custom-widget/flickr-widget.php');

$temp_root = get_root_directory('include/plugin/custom-widget/twitter-widget.php');

include_once($temp_root . 'include/plugin/custom-widget/twitter-widget.php');



// get the path for the file ( to support child theme )

function get_root_directory( $path ){

if( file_exists( STYLESHEETPATH . '/' . $path ) ){

return STYLESHEETPATH . '/';

}else{

return TEMPLATEPATH . '/';

}

}

?>
