Javascript 删除这个内置在购买的WordPress主题中的插件？

我正在为客户定制网站主题。当我去运行速度测试时，我注意到这段代码

<script type='text/javascript' src='http://s7.addthis.com/js/250/addthis_widget.js?domready=1&#038;ver=1'></script>

如果我删除了整个代码段，那么会有问题的代码和整个页脚都会消失。我试着移除支架内的所有东西，如下所示：

function footer(){ 
}

但令人不快的代码仍然出现了

同样在functions.php中-但是删除没有帮助

您是否尝试过搜索部分代码，比如addthis这个词？我尝试过，这是我第一次尝试。“addthis”仅在我发布的较长代码段的functions.php文件中显示，或作为一个类出现在其中一个样式表中。搜索
wp\u enqueue\u*
…我也尝试搜索wp\u enqueue\uu，但它们都与我尚未搜索“addthis”实例的脚本无关。请尝试查找一个代码段，该代码段打印出wp_footer（）上的所有注册操作或任何操作名称（请参阅wp_footer（）的定义）。
    <!-- footerwhat -->
    <?php wp_footer();  ?>
    <!-- footerwhat -->

    </footer>
    <!-- footer what?! END -->
    ...
    <script type='text/javascript' src='http://s7.addthis.com/js/250/addthis_widget.js?domready=1&#038;ver=1'></script>
    ...
    <!-- footer what?! END -->

<?php

 if (is_home() || is_front_page() ) { 
     remove_action('wp_footer', 'output_inline_js'); 
     wp_admin_bar_render(); 
     echo "<script type='text/javascript' src='http://yoursite.com/wp-content/themes/mercor/js/gistfile_pmc.js?ver=3.5.1'>‌​</script>
