Sign Out Link Disappeared

Discussion created by ykchin on Aug 21, 2013
This is a minor inconvenience.

On the Manager (10.2 Server), the Sign Out link at the upper right corner (where it used to be) disappear.
Right now, there are only esri.com | Resource Center | Help

Does anyone know what may be the cause and how to get the Sign Out link back?
