Joomla！ 3.4.5無法進入後端擴展管理器錯誤500

Question

我無法進入我的joomla！ 3.4.5後端的擴展管理器了！
我收到這個錯誤（與調試模式的信息）：

An error has occurred. 
     500 View class not found [class, file]: installerViewinstall, /var/www/vhosts/einserpasch.com/httpdocs/administrator/components/com_installer/views/install/view.html.php

10  JControllerLegacy->createView()    /var/www/vhosts/einserpasch.com/httpdocs/libraries/legacy/controller/legacy.php:863</code> 

在此之前，我遇到了一些問題，在安裝一個插件，所以我改變了我的行227 /httpdocs/libraries/joomla/filesystem/folder.php 從

$obd = ini_get('open_basedir'); 

到

//$obd = ini_get('open_basedir'); 

之後，我可以安裝我的p lugin。
我不知道這是否與我的擴展管理器問題有關。
但我解開了這個編輯folder.php，它並沒有解決這個問題。

自己解決的問題：
由於某種原因，view.html.php文件只是空的。
我在joomla 3.4.5安裝包的同一目錄中填充了來自同一文件的內容。
