Magento：Mage_Core_Exception无效的块类型：Mage_Banners_Block_Banners

Question

任何人都知道Magento安装的内容是什么？

更改了虚拟主机上的某些设置（与此特定网站的虚拟主机无关），之后此网站停止加载？

我更改了设置但页面仍然无法正确加载。

这是一个浏览器拍摄的样子，你可以看到，几乎是空白......

这是Magento投掷的日志：

这是nginx配置：

}

我不知道它为什么不加载！这让我把头发撕掉了！

Answer 1

我设法找出问题，在Magento开始在页面上抛出错误后说：

Parse error: syntax error, unexpected 'this' (T_STRING), expecting variable (T_VARIABLE) or '$' in 
/home/nginx/dutchbarnheadshop/public/app/design/frontend/default/fashionstore/template/page/html/header.phtml on line 52

所以我打开了header.phtml，如错误所示，发现了这个：

<?php echo $ this -> getChildHtml('qbanner.top') ?>

正如你所看到的，$和this之间的空间是不需要的，所以我删除了它，重新启动了php5-fpm并再次工作了！

我认为这是因为这个特定文件是由php5-xcache缓存的，当我昨天重新启动服务器时，缓存显然已被删除。当它尝试重新加载此文件时，该文件出现语法错误。

感谢大家的建议！
