[Uncaught ReferenceError: initPage is not defined]

No AD blocker active, I tried the IE, chrome, firefox several browsers, and also tested on other computers, will appear the problem.After clearing the browser cache can be normal use for a period of time, but then the problem will appear.
IE has a feature "always refresh from service", open the function can be normal use.

后台管理系统在使用了一段时间之后，就会出现这样的报错，并且顶部的菜单栏的样式出现问题，可以正常登录，登录之后同样是样式出错。

如果清除浏览数据之后，就能够正常使用，但使用几分钟之后又会出现该问题。
