redmine-2.6.3 报错 Incomplete response received from application

[relunctance]

不知道如何解决redmine报错问题

正常访问redmine没有问题


当提交表单后, 报错 Incomplete response received from application


redmine安装流程见: http://blog.csdn.net/gl145698789/article/details/50636538

查了下资料说是 SECRET_KEY_BASE 变量问题

但是没有解决问题

请告知下如何解决 , 着急
