当我在www.newswars.org上访问wp-admin时，我看到以下错误：

警告：无法修改标头信息 - 已经发送的标头（/home/newswars/public_html/wp-content/themes/videoplus/functions.php:38中的输出）/ home / newswars / public_html / wp-includes第563行/option.php

警告：无法修改标头信息 - 已经发送的标头（/home/newswars/public_html/wp-content/themes/videoplus/functions.php:38中的输出）/ home / newswars / public_html / wp-includes第564行的/option.php

你能帮忙吗？

编辑：好的，这就是问题所在。

$user_ej = wp_get_current_user();
if ($user_ej->roles[0] == 'contributor')
{ ?>

这是36-38行。由于某些原因，它搞砸了。我还不太清楚问题是什么。我试过删除？＆gt;但这给了我一个语法错误。我不知所措。这绝对是问题领域，因为只有当有人登录“贡献者”时才会出现。

add_shortcode("snap", "wpr_snap");
$user_ej = wp_get_current_user();
if ($user_ej->roles[0] == 'contributor')
{ ?>
  <style type="text/css">
    #menu-dashboard, #toplevel_page_wpcf7, #menu-tools 
    {
        display:none;
    }
</style>
<?php }
add_filter(  'gettext',  'change_post_to_portfolio'  );
add_filter(  'ngettext',  'change_post_to_portfolio'  );

不在函数内部。因此，只要文件加载就会调用它。这意味着所有输出都立即发送到屏幕。这个东西应该在一个函数内，然后在正确的时间调用（就像其他位一样）。
