WordPress 关闭后台主题、插件、系统自动更新与提示-www.88531.cn资享网

有时候会发现wordperss后台越来越卡，是什么原因呢？原因可能很多，但是一些更新的获取可能是其中之一。那么可以按需关系这些更新。

将以下代码加入主题的functions.php里（最后一个 ?> 之前）：

class OS_Disable_WordPress_Updates {   private $__pluginsFiles;   private $__themeFiles;    /**   * The OS_Disable_WordPress_Updates class constructor   * initializing required stuff for the plugin   *   * PHP 5 Constructor   *   * @since 1.3   * @author scripts@schloebe.de   */   function __construct() {   $this->__pluginsFiles = array();   $this->__themeFiles = array();      add_action( 'admin_init', array(&$this, 'admin_init') );    if( !function_exists( 'get_plugins' ) ) require_once ABSPATH .

  }  }    if ( class_exists('OS_Disable_WordPress_Updates') ) {   $OS_Disable_WordPress_Updates = new OS_Disable_WordPress_Updates();  }

以上代码是一个插件里的代码，插件名称好像是 disabled wordpress updates 。但是，我们能不用插件就尽量不用插件！
