我复制了一个开箱即用的材料＆＃34;主题和创建我的新主题基于相同。 当我尝试创建新网站时，它会显示在列表中。但是当我选择一个主题并点击＆＃34;创建＆＃34;它给了我一个错误。
Lumene错误日志如下所示：
[2016-10-22 06:44:57] lumen.ERROR：exception＆＃39; ErrorException＆＃39;带有消息＆＃39;未定义的变量：main_content＆＃39;在C：\ xampp \ htdocs \ respond \ app \ app \ Respond \ Models \ Page.php：652
我已经在我的页面中创建了一个html标签main，还有一个div具有role =＆＃34; main＆＃34;但似乎我仍然缺少一些东西。
有人可以指导我查看正确的问题。
Stacktrace就在这里：
