Question

我访问帮助文档里面的示例出现404：

Answer 1

你直接访问iportal页面能显示吗，http://localhost:8091/iportal

Comments

可以

但是如果登录后，只能访问后台，前台访问变成空白页

我部署的是SuperMap iPortal 9D(2019) for Windows(64位)

登录后 是指访问不了http://localhost:8091/iportal  能访问http://localhost:8091/iportal/manager这页面，访问空白，程序报什么错？

---

对

页面上没报错

你有修改里面的代码吗

---

没改之前就这样了...

先帮我解答下第一个问题吧

---

找到原因了，是iportal V9.1.0测试版本的问题，请问正式版什么时候会发布？

具体时间还没有确定，大概在9月底
