Upgraded from 11.0.1 to 11.0.4 and I'm getting a blank screen. This is a single server setup, using IIS. I've gone through the install documentation and I'm not finding anything.
Update:
If I go to the FQDN with /alias/bi/ from the server it works, but the same url on an outside computer just loads a blank page, it shows the cognos 11 icon in the url bar.
For anyone else:
Following this guide I was able to fix the white screen problem. I've run into some other issues, but it's unrelated as far as I can tell.
