Home / PHP & Wordpress / wordpress升级后加载缓慢s.w.org

<< SQL数据库替换命令普外科医师之元宵灯谜 看你能猜对几个 >>

更新wordpress4.4后，网站首页加载速度明显减慢，在浏览器的加载项里发现总是在加载s.w.org而导致网站打开缓慢。百度了一下发现是因为4.2的版本中添加了表情功能后加载的脚本。这个表情功能对多数人来说基本上没有用，反而拖累了网站速度。于是乎，百度到了一段代码就简单的解决了这个问题，需要的朋友们不妨试试。

将以下代码直接添加到主题的functions.php文件中即可去除该脚本！（后台——外观——编辑——functions.php），保持后首页明显提速。

  1. function disable_emoji9s_tinymce( $plugins ) {
  2.  if ( is_array( $plugins ) ) {
  3.  return array_diff( $plugins, array( ‘wpemoji’ ) );
  4.  } else {
  5.  return array();
  6.  }
  7. }
  9. function remove_emoji9s() {
  10.  remove_action( ‘wp_head’, ‘print_emoji_detection_script’, 7 );
  11.  remove_action( ‘admin_print_scripts’, ‘print_emoji_detection_script’ );
  12.  remove_action( ‘wp_print_styles’, ‘print_emoji_styles’ );
  13.  remove_action( ‘admin_print_styles’, ‘print_emoji_styles’ );

  17.  add_filter( ‘tiny_mce_plugins’, ‘disable_emoji9s_tinymce’ );
  18. }
  20. add_action( ‘init’, ‘remove_emoji9s’ );
  22. function custom_smilie9s_src( $old, $img ) {
