安装wordpress插件，提示报错“wordpress发生意外错误，可能或服务器配置文件存在问题”
出问题的页面是http://*.*.*.*/wp-admin/update.php?action=install-plugin&plugin=bbpress&_wpnonce=39e9668a43
查看/wp-admin/update.php这个文件，处理action=install-plugin这个get请求的代码如下
} elseif ( 'install-plugin' == $action ) {if ( ! current_user_can('install_plugins') )wp_die( __( 'You do not have sufficient permissions to install plugins on this site.' ) );include_once( ABSPATH . 'wp-admin/includes/plugin-install.php' ); //for plugins_api..check_admin_referer( 'install-plugin_' . $plugin );$api = plugins_api( 'plugin_information', array('slug' => $plugin,'fields' => array('short_description' => false,'sections' => false,'requires' => false,'rating' => false,'ratings' => false,'downloaded' => false,'last_updated' => false,'added' => false,'tags' => false,'compatibility' => false,'homepage' => false,'donate_link' => false,),) );
继续查看wp-admin/includes/plugin-install.php的plugins_api方法：
if ( false === $res ) {$url = $http_url = '/plugins/info/1.0/';if ( $ssl = wp_http_supports( array( 'ssl' ) ) )$url = set_url_scheme( $url, 'https' );$http_args = array('timeout' => 15,'body' => array('action' => $action,'request' => serialize( $args )));$request = wp_remote_post( $url, $http_args );if ( $ssl && is_wp_error( $request ) ) {trigger_error( __( 'An unexpected error occurred. Something may be wrong with or this server’s configuration. If you continue to have problems, please try the <a href="/support/">support forums</a>.' ) . ' ' . __( '(WordPress could not establish a secure connection to . Please contact your server administrator.)' ), headers_sent() || WP_DEBUG ? E_USER_WARNING : E_USER_NOTICE );$request = wp_remote_post( $http_url, $http_args );}if ( is_wp_error($request) ) {print_r($request->error_data);echo $request->errors;$res = new WP_Error('plugins_api_failed', __( 'An unexpected error occurred. Something may be wrong with or this server’s configuration. If you continue to have problems, please try the <a href="/support/">support forums</a>.' ), $request->get_error_message() );} else {$res = maybe_unserialize( wp_remote_retrieve_body( $request ) );if ( ! is_object( $res ) && ! is_array( $res ) )$res = new WP_Error('plugins_api_failed', __( 'An unexpected error occurred. Something may be wrong with or this server’s configuration. If you continue to have problems, please try the <a href="/support/">support forums</a>.' ), wp_remote_retrieve_body( $request ) );}
经过了一下午的挣扎，然后想，访问wordpress的时候一直比较慢，是不是连接超时了呢？
在上ping ，找了一个比较快的ip地址66.155.40.186，配置到/etc/host中，果然好了
祝病魔早日战胜方校长！！！！！！
