根据你的系统或网络设置Drupal不能读取网页，造成功能缺失。可能是web服务器配置或PHP设置引起的，可用更新、获取更新源、使用OpenID登 录或使用其他网络服务的下载信息都需要解决这个问题。若确定Drupal可正常读取网页但仍然出现此消息，你可以在你的 settings.php 文件底部添加 $conf['drupal_http_request_fails'] = FALSE;。

Your Status report page located at admin/reports/status returns the following error

HTTP request status Fails
Your system or network configuration does not allow Drupal to access web pages, resulting in reduced functionality. This could be due to your webserver configuration or PHP settings, and should be resolved in order to download information about available updates, fetch aggregator feeds, sign in via OpenID, or use other network-dependent services.

在settings.php（修改只读权限） 中末尾添加这一句
