If you are frequently logged out of your session, you can adjust idle the timeout in the user settings (top-right corner); for admin http://localhost:9000/primeRadiant/account/user/2.
The timeout is specified in seconds. If you need a different value, add a new
user_timeout TagValuePair at http://localhost:9000/primeRadiant/utils/tagValuePair/all.
A value of
28800 will keep the session open for 8 hours -- more than enough for a work day. Of course this is idle time, when you refresh a page or interact the website, the timeout resets.
