Here’s an issue that’s popped up a couple of times for me, and I figured was worth of note.
Upon navigating to the Project Center view in Microsoft Project Server 2010, I see that the ribbon is greyed out and inactive. A small error notice appears in the bottom left of the screen stating. When I click on the icon, it gives me the following message.
User Agent: Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1; WOW64; Trident/4.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; InfoPath.2; MS-RTC LM 8; .NET4.0C; .NET4.0E; InfoPath.3)

There may be a couple of reasons for this to occur. The most common one that I’ve run into is that this will occur when a solution starter that appears on the ribbon is uninstalled from the server. As far as I can tell, this leaves a cached version of the ribbon on your local client IE – which throws an error on load.
Luckily the fix is quite easy. Simply delete your local IE cache, refresh the page, and everything is back to normal.
