Magento 2主题在显示空白的联系页面上打破了参考

Question

我在联系页面中关于Magento 2自定义主题的FE有问题。主题基于原始亮度主题。当我在自定义主题中打开联系页面时，它显示为空白，但在Luma主题中它正常工作。我不知道从哪里开始调试。我遇到的错误就在这里。

[2016-05-18 08:34:06] main.INFO: Cache file with merged layout: LAYOUT_frontend_STORE1_40a98983867a1770682b48d9a0ad63441: Please correct the XML data and try again.  [] []

我还在后端联系表格中创建了模板并将其链接到网站。
