【问题描述】：
我正在使用模板怪物的主题，我已成功从 2.1.7 升级到 2.2.6 我使用通过命令行升级。 技术是 Centos 7 上的 PHP 7.1.3。 我可以很好地进入后端并登录，一切似乎都在工作（仅限后端）。
但是前端只显示一个空白页面 - 我尝试了几种更改权限的方法，包括 chmod -R 777 /var/www/html/magento2 - 我以不同的顺序多次刷新、升级、编译、索引和部署 - 我的日志文件显示了一些警告，我不确定这是导致空白屏幕的原因
这里是

我最大的问题是我不知道如何记录此问题以便进行调试。我得到的只是一些损坏的引用，这是导致问题的原因吗？
如何解决黑屏问题？
编辑：我升级到 PHP 7.2.27，删除了所有静态文件并将主题更改为空白，再次部署所有内容。 我通过更改此代码编辑了 Validator.php
$realPath = str_replace('\\', '/', $this->fileDriver->getRealPath($path));
不幸的是，仍然没有运气。
