由于 FOSUserBundle，生产模式下的 Symfony2 不工作
Symfony2 in production mode doesn't work because of FOSUserBundle
我正在尝试将我的大学 symfony2 项目部署到我的生产服务器。在开发模式下，一切正常。
所以我通过 git 将项目从我们的服务器克隆到我的主机上。 parameters.yml 配置良好，作曲家是最新的，固定装置也已加载到数据库中。
当我通过 http 调用 web 文件夹时，symfony2 显示一个空白页面。 prod.log 简述如下：

我尝试了哪些修复方法？
- 删除
app/cache/*
- 再次删除
vendor/*和运行composer update
服务器（开发和生产）运行 PHP 5.6.12
谁能告诉我问题出在哪里？
“解决方案”：
将 libxml_disable_entity_loader(false); 添加到 web 文件夹中的 app.php。
在 github issue 上找到了解决方法。

我尝试了哪些修复方法？
- 删除
app/cache/* - 再次删除
vendor/*和运行composer update
服务器（开发和生产）运行 PHP 5.6.12
谁能告诉我问题出在哪里？
“解决方案”：
将 libxml_disable_entity_loader(false); 添加到 web 文件夹中的 app.php。
在 github issue 上找到了解决方法。
