【中文标题】在 Joomla 上出现错误：无法读取会话数据和应用程序实例化错误

【英文标题】：Getting Error on Joomla: Failed to Read Session Data and Application Instantiation Error

【发布时间】：2018-08-07 23:44:47

【问题描述】：

我正在尝试在本地主机上运行我的 Joomla 网站，但出现以下错误：

警告：session_start()：读取会话数据失败：用户（路径：C:\xampp\tmp）在 C:\xampp\htdocs\Joomla_3\libraries\joomla\session\handler\native.php在第 258 行 显示错误页面时出错：Application Instantiation Error: Failed to start the session

我试图通过 Internet 找到解决方案，并对“configuration.php”文件进行了一些更改，但仍然一次又一次地出现相同的错误： 这是我的配置。文件：

这里是 index.php 文件：

<?php
    define('JOOMLA_MINIMUM_PHP', '5.3.10');

if (version_compare(PHP_VERSION, JOOMLA_MINIMUM_PHP, '<'))

    die('Your host needs to use PHP ' . JOOMLA_MINIMUM_PHP . ' or higher to run this version of Joomla!');


// Saves the start time and memory usage.
$startTime = microtime(1);
$startMem  = memory_get_usage();

/**
 * Constant that is checked in included files to prevent direct access.
 * define() is used in the installation folder rather than "const" to not error for PHP 5.2 and lower
 */
define('_JEXEC', 1);

if (file_exists(__DIR__ . '/defines.php'))

    include_once __DIR__ . '/defines.php';


if (!defined('_JDEFINES'))

    define('JPATH_BASE', __DIR__);
    require_once JPATH_BASE . '/includes/defines.php';


require_once JPATH_BASE . '/includes/framework.php';

// Set profiler start time and memory usage and mark afterLoad in the profiler.
JDEBUG ? $_PROFILER->setStart($startTime, $startMem)->mark('afterLoad') : null;

// Instantiate the application.
$app = JFactory::getApplication('site');

// Execute the application.
$app->execute();

我想知道我的网站没有在 localhost 上运行的原因？ 感谢您的帮助。

【参考方案1】：

将mysql文件夹移动到另一个挂载后我遇到了同样的错误，我不得不将configuration.php中的$host从'localhost'更改为'127.0.0.1'，解决了它。

【参考方案2】：

正如我在你看到的配置 $host 是正确的，所以它可能是不同的原因。但对我来说，解决方案是删除 $host 变量中 configuration.php 中的 : 符号。
