I received a nice Happy New Year from my Project Server 2010 today. I tried to navigate to the root site and received the following error.
Error
The base type 'Microsoft.Office.Project.PWA.PJBaseWebPartPage' is not allowed for this page. The type is not registered as safe.

I did some searching and found that it could be one of 2 things
1. App Pool security
2. Custom Master page.
All the sub-sites seem to work fine, so I went with option 2. I changed the Master page of the root site back to v4.master and everything works fine again.
So far the only solution I found to allow for using a Custom master page is to modify the web.config as suggested here:http://jimecox.wordpress.com/2011/05/03/project-server-2010-changing-master-page/
My custom master was working fine for the past 6 months, so I’m not sure why I need to make this new update.
Anyone else run into this recently with another fix? The changes seem to be opening the security on the Project web app a bit or am I wrong?
Thank you in Advance!
