Hi All.
Long time lurker first time poster.
This is not a request of solving an issue. This is a heads up to solve a very particular issue
Anyone who has upgraded to Cognos 11 Analytics and entered into the Administration Console only to see a unformatted web page missing icons (replaced by a cross) etc. Then this is the fix for you.
Turns out in Cognos 10 if you set a skin under my preferences as a custom skin, then the upgrade occurs and the skin is removed or deleted or not carried forward. Then the above problem occurs. If you create a new AD account and log into admin with that new account the problem goes away, but then so does all of your access emails etc.
So within Administration Console in the top right there is a little person icon (or on the un-formatted screen its the first cross next to the circular refesh button). Click or double click that. Now on the un-formatted screen down the bottom of the screen you will see a my preferences. Again click or double click.
You will now see the my preferences tab. Change the "Style" to Corporate and you will have a fully formatted admin screen back. This was identified though clicking F12 and seeing the skin reference in the first 10 lines of code referring to an old skin.
Hope this helps some one else because it took a while to fix here.
