Have similar issue (posted here a few days ago) and still have not been able
to find cause or solution....
here is a copy of my POST:
Project Server 2007/SP1
Have three users who up to yesterday use PWA on a daily basis.
Something changed... they still have ability to log on to PWA but when they
click "My Task" they get the following error message...
An unexpected error has occured.
WEB PARTS MAINTENANCE PAGE: If you have permission you can use this page to
temporarily close WEB Parts or remove personal settings. For more
information contact your administrator.
I have reset their security settings and short of deleting their logon (and
recreating) I not sure where to go from here
