Blank Page in the Pyramid Website After a Successful Installation (Versions Older than 5)
Cannot access the web site after a successful installation.
The installation process was successful (setup and configuration wizard didn't have any errors).
After the installation is completed and you try to reach the admin site, you get a blank (white) page and the little yellow error triangle appears in the bottom left of the screen (IE).
This usually means that some IIS role services (features) are missing.
view the image attached to see what components you need to add.
First thing to check is that all the IIS role services (features) are installed.
Mainly the security features (Windows authentication, basic authentication, and anonymous authentication),
also the management tools and management compatibility.
