return to log in again to access the system.
If it has been less than a day since you last logged in, there are other common
reasons you may be seeing this error:
A pop-up blocker is preventing reports and other information from opening in a
new window.
Another session has been created with your username/password; your username and
password have been used to login in a different browser or by someone else, or you
may have logged out and closed your session.
