One annoying aspect of the back end in Joomla is that by default, it times out after 15 minutes of inactivity, and you have to log in again. That happens more often than you may think. You may find yourself keeping a back-end window open while you monitor other things on the site — and the next thing you know, you’re being asked to log in again.
Fortunately, when you are unexpectedly logged out, Joomla 1.6 does its very best to ensure that once you log back in, you’ll be returned as close as possible to the last thing you worked on. For multitaskers, this feature will become a fast favorite.
You can change this timeout setting easily, however. To do that, follow these steps:
1. Choose Site➪Global Configuration in any back-end page to open the Global Configuration page.
2. Click the System tab at the top of the page.
3. In the Session Settings section, change the Session Lifetime setting. You may want to change it to as much as 60 (minutes) if you’re getting a lot of annoying timeouts.
4. Click Save & Close.
