developer portal in azure management api is not correctly working

Question

Why it is that when clicking on API, it is displaying the popup as shown in the picture, rather then going to the API page?
I have publish the project and reset content but then also no change?
How can I activate the site?
It seems to me that some setting is still remaining

Answer 1

You open the developer portal as administrator :

Follow the steps below to access the managed version of the portal.
In the Azure portal, navigate to your API Management instance.
Select the Developer portal button in the top navigation bar.
A new browser tab with an administrative version of the portal will open.

In this administrative version of the developer portal, you are able to modify the look & feel,...

If you want to use the developer portal as a usual user, you have to open the developer portal in a browser with private mode or with a different browser and sign in.
