这让我困扰了一段时间，我找不到其他人遇到和我一样的问题，
我已经安装了DjangoCMS 3.0.2并且就此而言，我尝试使用cmsplugin_contact（我已经完成了整合并且网页加载正常）。它似乎在调试模式下工作正常，在提交时显示感谢信息。当我将DEBUG标志翻转到False时，事情就会出错。
Apache服务器提供了一个错误＆＃39;，这意味着请求成功，但随后突然发生了一些事情。检查错误日志中的回溯，CMS标签似乎是罪魁祸首。显然，request对象没有通过，我不明白为什么。
这里是追溯：

此问题也出现在我不使用cmsplugin_contact模块之前，但通过设置ALLOWED_HOSTS值并注释掉TEMPLATE_DEBUG = DEBUG标志来解决。现在，它似乎没有用。有什么想法吗？
