We recently upgraded from TFS 2012 Update 2 to TFS 2013 Update 4.
After the upgrade, users are having intermittent issues trying to load Web Access - for some users, only the header loads, but none of the information below (like work items, for example) loads - the entire screen basically stays blank.
This is happening on different browsers for different people. Clearing caches has worked for some users and not others, and for some people the problem has come back after being able to load Web Access normally a couple days ago.
I do see this error popping up when debugging:
No define call received from module Presentation/Scripts/TFS/TFS.DataServices. This might be a problem.
What can I do to correct this?
