Admin Page is Empty after installation

I installed Openfire 3.5.1 on a newly installed Windows Server 2008.

I clicked on Openfire-Server and it started up. I clicked on the admin page button and the site loads.

But it’s completely empty. No error. Only an Empty web site with no body. What I’m doing wrong?

Thx for your help

When you click the button for the admin panel, is it taking you to http://127.0.0.1:9090? if so try changing the http://127.0.0.1:9090 to http://localhost:9090 or the machine name eg http://openfire:9090. I had the same problem and this corrected it.

What say in the log files? Why not install v3.6.3?

did you punch all the needed holes in the firewall?
