所以我更新了我的插件，然后我卸载了我的Sliding Widgets插件，现在我在管理面板和我网站的标题上方收到以下警告消息：
Warning: include(shortcodes.php): failed to open stream: No such file or directory in /homepages/14/d442309306/htdocs/app572581842/wp-content/themes/shopkeeper/functions.php on line 2
Warning: include(): Failed opening 'shortcodes.php' for inclusion (include_path='.:/usr/lib/php5.5') in /homepages/14/d442309306/htdocs/app572581842/wp-content/themes/shopkeeper/functions.php on line 2
关于如何纠正这个问题的任何想法？
更新： 我的functions.php中的前几行是：
<?php
include('shortcodes.php');
// theme textdomain - must be loaded before redux
load_theme_textdomain( 'shopkeeper', get_template_directory() . '/languages' );
但我对include('shortcode.php');发表了评论，看看会发生什么。它使警告从我网站的标题上方发出，这很棒，但是现在在我的登录页面上，我只会在页面上显示以下警告，并且无法再登录：
Warning: Cannot modify header information - headers already sent by (output started at /homepages/14/d442309306/htdocs/app572581842/wp-content/themes/shopkeeper/functions.php:1) in /homepages/14/d442309306/htdocs/app572581842/wp-includes/pluggable.php on line 1196
我的functions.php目前是什么样的：
<?php
// include('shortcodes.php');
// theme textdomain - must be loaded before redux
load_theme_textdomain( 'shopkeeper', get_template_directory() . '/languages' );
