html文档中的空线 - wordpress

Question

我刚刚启动了新网站。一切正常，但是，我刚刚注意到HTML文档（页面的源代码）在“ ＆lt;！doctype html＆gt;”之前有15行。这引起了SEO的一些问题并生成自动站点地图。

我在网上搜索，最后找到了问题：我的孩子主题（店面）中的function.php。当我在子主题中删除或重命名function.php时，通常显示HTML DOC，没有空白空间。我尝试一个一个一个删除文件中编码的函数，但是问题仍然存在，直到我将所有函数删除为止。另外，我禁用了所有插件，什么也没有解决，只删除上述文件。有什么想法吗？非常感谢！

以下是functions.php的当前内容

add_filter( 'woocommerce_product_tabs', 'my_remove_all_product_tabs', 98 );
function my_remove_all_product_tabs( $tabs ) {
  unset( $tabs['description'] );        // Remove the description tab
  unset( $tabs['reviews'] );       // Remove the reviews tab
  unset( $tabs['additional_information'] );    // Remove the additional information tab
  return $tabs;
}

我很抱歉。现在解决了，我发现问题是每个PHP打开/关闭之间的空白线。对不起，无用的帖子。
问候！
