更改数据库后TYPO3网站不起作用 [英] TYPO3 website doesn't work after changing db

问题描述

我想复制我的 TYPO3 CMS 6.2.18 网站 - 到目前为止我所做的:

I want to make a copy of my TYPO3 CMS 6.2.18 website - what I did so far:

1. 复制整个网站文件夹(包括 TYPO3 安装)
2. 复制整个数据库(使用新名称)
3. 为复制的数据库创建一个新的数据库用户
4. 根据新的 DB+User 调整文件 /typo3conf/LocalConfiguration.php

现在我在调用我复制的 TYPO3 网站的不同网址时收到以下错误:

Now I'm receiving following errors when calling different urls of my copied TYPO3 website:

当我尝试从安装工具/typo3/install(这是当前唯一可用的页面)内部调用升级向导"时:

When I try calling the "Upgrade Wizard" from inside the install tool /typo3/install (which is the only page that currently works):

#1: PHP Warning: count(): Parameter must be an array or an object that implements Countable in /var/www/vhosts/<my-domain>/typo3/sysext/install/Classes/Service/SqlSchemaMigrationService.php line 409

当我调用 /typo3

 #1: PHP Warning: count(): Parameter must be an array or an object that implements Countable in /var/www/vhosts/<my-domain>/typo3/sysext/backend/Classes/Utility/BackendUtility.php line 3022
4 count(NULL)
...
/var/www/vhosts/<my-domain>/typo3/sysext/backend/Classes/Utility/BackendUtility.php:
03020:   $signals = array();
03021:   $modData = $GLOBALS['BE_USER']->getModuleData('TYPO3\\CMS\\Backend\\Utility\\BackendUtility::getUpdateSignal', 'ses');
03022:   if (!count($modData)) {
03023:    return '';
03024:   }

当我调用

#1: PHP Warning: count(): Parameter must be an array or an object that implements Countable in /var/www/vhosts/<my-domain>/typo3/sysext/core/Classes/Database/PreparedStatement.php line 582
...after calling... 
TYPO3\CMS\Core\Database\PreparedStatement::convertNamedPlaceholdersToQuestionMarks("SELECT * FROM fe_session_data WHERE hash = :hash", array, array)

我感兴趣的是:
复制网站后，该副本有效，只有在将其引用到复制的数据库后才显示这些错误.

What's interesting to me:
After copying the website the copy worked, only after referencing it to the copied db it showed these errors.

有人知道我可以做什么/正在寻找什么吗?
我尝试删除所有缓存、安装工具清理"部分中显示的所有表以及typoe3temp 文件夹中的所有文件.

Anyone an idea what I could do / be looking for?
I tried deleting all cache, all tables shown in the "Cleanup" part of the install tool and all files in the typoe3temp folder already.

推荐答案

所以，正如我在评论中所说的.可能是 PHP 版本的问题，因为所有提到的错误(实际上是警告；))反映了不兼容的 PHP 代码.

So, as I have said in the comment. Probably the issue with PHP version, because of all the mentioned errors (warning actually ;) ) reflect the incompatible PHP code.

解决方案很简单，根据TYPO3的需要切换你的PHP版本:)

The solution is pretty easy, switch your PHP version according to TYPO3's need :)
