我完全没有办法解决这些问题，迫切需要帮助。
我准备在新的（文件夹）位置将我的prestahsop 1.4.4升级到1.5。我安装了新的prestashop没有任何问题。它与我现有的prestashop位于不同的文件夹中。
但是自从安装以来我无法访问我现有的prestashop，无论是管理员还是商店。在那之前我没有任何问题。
这些是错误报告：

Language.php l554的代码是
foreach ($result AS $row)
这是/** Load all languages in memory for caching
FrontController.php l228的代码是
if ($cart->{Configuration::get('PS_TAX_ADDRESS_TYPE')})
Tools.php l104的代码是
header('Location: '.$url);
这是/** redirect to another admin page
Cookie.php l300的代码是
return setcookie($this->_name, $content, $time, $this->_path, $this->_domain, 0, true);
我希望这些信息足以让某人指出我正确的方向。我需要紧急援助。
非常感谢，

答案 0 :(得分：0)
这些问题可能有几个原因。您能否回答以下问题：
1）安装Prestashop 1.5时你是否为它创建了一个新的数据库，或者你使用的是与旧的prestashop 1.4相同的数据库？
2）您的Prestashop 1.5安装网站运行正常吗？
3）您是否阅读过http://doc.prestashop.com/display/PS15/Updating+PrestaShop和http://doc.prestashop.com/display/PS14/Updating+PrestaShop？
请在您的网站上启用错误，然后就可以看到确切的问题。
谢谢
